    2010-01-01

    Full Text Available Brachman de Lange syndrome or Cornelia de Lange syndrome (CdLS is a genetic disorder which can lead to severe developmental anomalies. It affects both the physical and intellectual development of a child. It is characterized by skeletal, craniofacial deformities, gastrointestinal and cardiac malformations. This syndrome is of rare occurrence and affects between 1/10,000 and 1/60,000 neonates. Diagnosis is based on the characteristic phenotype, in particular, a striking facial appearance, prenatal and postnatal growth retardation, various skeletal abnormalities, hypertrichosis, and developmental delay. Here, we present the case of a 13-year-old patient, with micrognathia, delayed eruption, multiple carious teeth, missing teeth and periodontal problems together, which had never been reported before. The father was also found to have the same missing teeth as the girl child.

  7. Gravity currents at Ormen Lange

    Energy Technology Data Exchange (ETDEWEB)

    Vikeboe, Frode; Berntsen, Jarle; Furnes, Gunnar

    2001-12-01

    Time series of temperature and velocities at Ormen Lange, located in the Storegga region off mid-Norway, indicate that close to the seabed, at depths ranging from 500-1000 m, large temperature fluctuations are accompanied by short peak values in speed. The extreme events are driven by strong pressure gradients, due to strong atmospheric low pressures and/or internal pressure fronts between warmer Atlantic Water (AW) and colder Norwegian Sea Water (NSW). Along the shelf slope at OL we may get steepening of the iso surfaces of density, separating AW and NSW, due to strong Ekman veering during storms or approaching internal density fronts. During such events the density surfaces tend to undershoot their equilibrium level, and as the forcing weakens, the suppressed water may run up along the shelf slope. In this run up phase, peak values in the velocities are often found. As a result of the run up phase, heavy water may be elevated onto the shelf. Subsequently dense fluid will spread under the influence of forces produced by its own buoyancy and motions of this form are often referred to as gravity currents. They are characterised by the distinctive nature of the front, which consists of a raised head leading a shallower flow behind. The shape of the head and body of the gravity current, along with velocity, depend on a range of parameters. This report investigates the velocities that may occur with parameters of relevance for Ormen Lange. (author)

  15. Lang's conjectures, conjecture H, and uniformity

    CERN Document Server

    Abramovich, D

    1995-01-01

    The purpose of this note is to wish a happy birthday to Professor Lucia Caporaso.* We prove that Conjecture H of Caporaso et. al. ([CHarM], sec. 6) together with Lang's conjecture implies the uniformity of rational points on varieties of general type, as predicted in [CHarM]; a few applications in arithmetic and geometry are stated. Let X be a variety of general type defined over a number field K. It was conjectured by S. Lang that the set of rational points X(K) is not Zariski dense in X. In the paper [CHarM] of L. Caporaso, J. Harris and B. Mazur it is shown that the above conjecture of Lang implies the existence of a uniform bound on the number of K-rational points of all curves of fixed genus g over K. The paper [CHarM] has immediately created a chasm among arithmetic geometers. This chasm, which often runs right in the middle of the personalities involved, divides between loyal believers of Lang's conjecture, who marvel in this powerful implication, and the disbelievers, who try (so far in vain) to use t...

    Cornelia de Lange syndrome is a rare genetic disease characterized by distinctive facial dysmorphia and dwarfism. Multiple organ system involvement is typical. Various central nervous system (CNS) aberrations have been described in the pathology literature; however, the spectrum of neuroimaging manifestations is less well documented. To present neuroimaging findings from a series of eight patients with Cornelia de Lange syndrome. The CT/MR database at a single academic children's hospital was searched for the terms ''Cornelia'', ''Brachmann'' and ''de Lange.'' The search yielded 18 exams from 16 patients. Two non-CNS and six exams without available images were excluded. Ten exams from eight patients were evaluated by a board-certified neuroradiologist. All patients had skull base dysplasia, most with an unusual coronal basioccipital cleft (7/8). All brain MR exams showed microcephaly, volume loss and gyral simplification (5/5). Six patients had an absent massa intermedia. Four patients had small globe anterior segments; three had optic pathway hypoplasia. Basilar artery fenestration was present in two patients; vertebrobasilar hypoplasia was present in one patient. The inner ear vestibules were dysplastic in two patients. One patient had pachymeningeal thickening. Spinal anomalies included scoliosis, segmentation anomalies, endplate irregularities, basilar invagination, foramen magnum stenosis and tethered spinal cord. Typical imaging manifestations of Cornelia de Lange syndrome include skull base dysplasia with coronal clival cleft, cerebral and brainstem volume loss, and gyral simplification. Membranous labyrinth dysplasia, anterior segment and optic pathway hypoplasia, basilar artery fenestration, absent massa intermedia and spinal anomalies may also be present. (orig.)

    Ormen Lange is the largest natural gas field in development on the Norwegian continental shelf. This paper discussed Norsk Hydro's Ormen Lange development strategy and execution. Several illustrations of the Ormen Lange project were presented, including the field layout and the main challenges of working in deep water. Other challenges involve environmental conditions; long distance control; and hydrate prevention. Several components of the project were presented, including the xmas tree handling system; choke module; control system; large bore tie-in system; in-line tee system; and free spans in pipeline design. Other topics that were presented and illustrated included the feasibility of pipeline design; design optimization with installation contractors; design optimization between intervention methods; positioning; dredging with spiders; excavation with jetprops; ploughing; rock installation; and trenching. The installation of thirty inch pipelines and umbilical lines in shallow and deep water were also discussed and illustrated. The presentation concluded with a discussion of lessons learned subsea. These included early definition of operational requirements; close monitoring of interface work between contractors; professional change management; and thorough testing onshore prior to installation. Securing vessel capacity and timely start-up were among the lessons learned for marine operations. figs.

  19. Environmental Survey at Ormen Lange, June 2009

    2010-07-01

    An environmental monitoring survey was carried out at Ormen Lange in Region V on behalf of Norske Shell. The samples were collected at 19 stations by use of a 0.25 m{sub 2} box corer and carried out in connection with the field work in Region VI. The station depths varied between 823 and 925 m. The sediments at Ormen Lange are classified as silt with a high amount of pelite (> 90 %) and TOM (> 9 %). The amount of pelite is higher than that found in the baseline survey in 2004 at all stations. Whether this is a result of changes in sediment composition or a difference in analytical methods used is not known. With the exception of station OL-01 and OL-09, where a small increase has occurred, the amount of TOM has decreased at the stations since 2004. The concentrations of hydrocarbons and metals in the sediments at Template D, can be regarded as the natural background level for these parameters. The average amount of THC in the sediments around Template D is 11.7 +- 1.8 mg/kg in this base line survey. The average level of THC at template A and B was at the same level in the base line survey in 2004, 9.7 +- 0.6 mg/kg. In the present survey the average amount of THC in the sediments at Template A and B has increased to 17.0 +- 3.9 mg/kg. 11 of 14 stations at Template A and B have slightly elevated levels of barium and zinc in the sediments and sediments at three stations are elevated with mercury. In the present survey the mollusks dominates the fauna at Ormen Lange. The number of individuals at the stations (0.4 m{sub 2}) is high (1553 - 2833), while the number of taxa is relatively low (51 - 73), resulting in a very low diversity (H' 2.4 - 3.3). This is due to the over dominance by two mussels (Thyasira minuta and T. equalis) at all stations. However, the dominant species registered are known to be abundant in sediment with high amount of pelite and organic material. Due to the different sampling strategy and area, a direct comparison with the baseline survey is

    Huang Lang chicken is the native breed of Hunan province in China. The complete mitochondrial (mt) genome sequence plays an important role in the accurate determination of phylogenetic relationships among metazoans. It is the first time that the complete mt genome sequence of the Huang Lang chicken was reported in this work, which was determined through the polymerase chain reaction-based method. The total length of the mitogenome is 16,786 bp, with the base composition of 30.25% for A, 23.71% for T, 32.53% for C and 13.51% for G, in the order C > A > T > G feature occurs in the Huang Lang chicken. It contains the typical structure, including two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and 1 non-coding control region (D-loop region). The complete mt genome sequence of the Huang Lang chicken provided an important data for further study on the genetic mechanism.

    Thirty-six de Lange patients aged 5-47 years with a median age of 16 years were tested by the Vineland Social Maturity Scale. Significant physical handicaps affecting the scoring were found in six patients. The social quotients varied from 2.2-99.5. Eighty-one per cent of the patients scored less than 52. Specific retardation was found in verbal communication. Other cognitive skills also showed low scoring, while the patients showed relatively high scores in self-help items. Fifteen patients lived in large institutions for the mentally retarded, three patients lived in hostels or boarding-schools, and one patient lived in her own home. Only two patients, both severely retarded, did not attend any regular daily activity. It is concluded that de Lange patients will not be able to live without support in the community, that they are particularly retarded in verbal communication but that they function relatively well in everyday self-help skills.

We report a case of JLNS in a child who presented to us with refractory epilepsy. The cardiac cause of seizures was suspected as the child was hypotensive and pulseless during the episode of seizures. The child was diagnosed as JLNS based on Schwartz diagnostic criteria for LQTS and congenital sensorineural deafness. The child responded well to β-blocker therapy. Antiepileptic drugs were stopped. The screening of family members with ECG revealed a QT interval more than required for diagnosis of LQTS but they were asymptomatic. All asymptomatic family members were also put on metoprolol. All of them showed great improvement with the reduction of the QT interval on ECG. The patient was doing well on immediate follow-up.

  5. Thinning sea ice weakens buttressing force of iceberg mélange and promotes calving

    Science.gov (United States)

    Robel, Alexander A.

    2017-01-01

    At many marine-terminating glaciers, the breakup of mélange, a floating aggregation of sea ice and icebergs, has been accompanied by an increase in iceberg calving and ice mass loss. Previous studies have argued that mélange may suppress calving by exerting a buttressing force directly on the glacier terminus. In this study, I adapt a discrete element model to explicitly simulate mélange as a cohesive granular material. Simulations show that mélange laden with thick landfast sea ice produces enough resistance to shut down calving at the terminus. When sea ice within mélange thins, the buttressing force on the terminus is reduced and calving is more likely to occur. When a calving event does occur, it initiates a propagating jamming wave within mélange, which causes local compression and then slow mélange expansion. The jamming wave can also initiate widespread fracture of sea ice and further increase the likelihood of subsequent calving events. PMID:28248285

    This report describes a numerical model for the simulation of circulation at the Ormen Lange oil field. The model uses a topography following vertical coordinate and time split integration procedure. The model is implemented for a 28 km x 46 km area at Ormen Lange. The equations are given in detail and numerical experiments are discussed. The numerical studies investigate how the flow specified at open boundaries surrounding the Ormen Lange area may be interpolated into the interior domain taking into account the conservation laws that are believed to determine the flow and the local topography.

  9. Mechanical effect of mélange-induced buttressing on embayment-terminating glacier dynamics

    Directory of Open Access Journals (Sweden)

    D. Seneca Lindsey

    2012-09-01

    Full Text Available Embayment terminating glaciers interact dynamically with seasonal sea ice and icebergs, a mixture we refer to as mélange. For certain glaciers, mélange prevents calved bergs from rotating away from the front, thus allowing the ice front to advance into the embayment. Here we demonstrate that mélange can, if rigid enough, provide sufficient buttressing to reduce the calving rate, while leaving the ice-front velocity largely unaffected. The net result is additional ice-front advance.

    Observations indicate a seasonal advance/retreat cycle has occurred at Jakobshavn Isbræ since the 1950s. We model an idealized Jakobshavn Isbræ-like scenario and find that mélange may be responsible for a seasonal ice-front advance of up to 0.6 km. These results come from a model that incorporates mélange into the interior of the domain, includes relevant stresses, and models drag via a kinematic boundary condition. A weakening or loss of mélange due to increasing temperatures would lead to further mass loss from glaciers such as Jakobshavn Isbræ.

  12. Repensar la criminología con Luhmann, Lang, Foucault

    Directory of Open Access Journals (Sweden)

    Luciano Nuzzo

    2013-01-01

    Full Text Available El tema que el artículo afronta es: ¿cuál es el objeto de la criminología? Para responder a esta pregunta es necesario analizar el estatuto epistemológico delsaber criminológico. Pero si se busca una respuesta a este problema dentro del debate criminológico, se quedará desilusionado. La criminología parece no darse plenamente cuenta de la necesidad de un método capaz de hacer posible una comprensión de su propio objeto. El autor propone seguir tres caminosque, desde perspectivas diferentes, afrontan el problema fundamental para cada observación social, es decir, el hecho de que cada observación de la sociedad es parte de lo que se quiere describir. El primer recorrido propuesto es la teoría de los sistemas sociales de Niklas Luhmann. Mediante la distinción entre observación de primer y de segundo orden es posible comprender el problema del objeto sin caer en la paradoja de la autoimplicación. El segundo recorrido propuesto es una obra de arte y precisamente el film de Frit Lang M., El monstruo de Dusseldorf. El arte, en efecto, permite ver lo que no podemos ver dentro de los confines de una observación científica. El arte permite rodear el punto ciego de la propia observación. Por último, el tercer recorrido propuesto al lector es la genealogía del poder descrita por Michel Foucault en el curso al College de France de 1974-1975, dedicado a los Anormales Estos tres recorridos permiten comprender desde perspectivas diferentes que la criminología no podrá producir conocimientos suficientemente adecuados a su objeto si no comprende cómo ella misma está siempre implicada en la construcción del objeto que observa.

    Barrett's esophagus, a premalignant condition, is recognized as stratified squamous epithelium of the esophagus substituted by columnar epithelium. The risk factors for development of Barrett's esophagus include frequent gastroesophageal reflux, esophageal stricture, male sex and mental retardation, but there is no report of Barrett's esophagus in children with de Lange syndrome. We report a 7-year-old boy who was diagnosed as de Lange syndrome shortly after birth and had gastroesophageal reflux since early infancy. Upper gastrointestinal endoscopic examination revealed a cauliflower-like mass and a pink-red velvety mass over the lower third of the esophagus. Biopsy showed goblet cells metaplasia, confirming Barrett's esophagus. We suggest surveillance of Barrett's esophagus could be done ahead of schedule in children with long-standing gastroesophageal reflux or with de Lange syndrome.

    Teo, Thomas

    2002-01-01

    Friedrich Albert Lange was a German philosopher, political theorist, educator, and psychologist who outlined an objective psychology in the 1860s. This article shows how some of the most important worldviews of the nineteenth century (Kantianism, Marxism, and Darwinism) were combined creatively in his thought system. He was crucial in the development of neo-Kantianism and incorporated psycho-physiological research on sensation and perception in order to defend Kant's epistemological idealism. Based on a critique of phrenology and philosophical psychology of his time, Lange developed a program of a psychology without a soul. He suggested that only those phenomena that can be observed and controlled should be studied, that psychology should focus on actions and speech, and that for each psychological event the corresponding physical or physiological processes should be identified. Lange opposed introspection and subjective accounts and promoted experiments and statistics. He also promoted Darwinism for psychology while developing a socialist progressive-democratic reading of Darwin in his social theory. The implications of socialist Darwinism on Lange's conceptualization of race are discussed and his prominence in nineteenth century philosophy and psychology is summarized.

    Full Text Available The long-standing friendship between Andrew Lang (1844-19121 and Henry RiderHaggard (1856-19252 is surely one of the most intriguing literary relationships ofthe Victorian era.3 Lang was a pre-eminent literary critic and his support forHaggard’s earliest popular romances, such as King Solomon’s mines (1885 andShe (1887, helped to establish them as leading models of the new genre ofimperial adventure fiction.4 Lang and Haggard co-authored The world’s desire(18905 and the ideas of Lang, who was also a brilliant Classics scholar, can beseen in many of Haggard’s works. There are some significant similarities betweenthe two men: both were approximate contemporaries who lived through the mostaggressive phase of British imperialism, both were highly successfully writers whoearned their living by their pens, both wrote prolifically and fluently on a wide range of subjects,6 both were largely self-educated, both were interested in thesupernatural, both had had unhappy experiences in love at first but later maintainedlong-lasting marriages, and both were men with powerful faculties of imagination.There are, of course, significant differences also: Lang was a gifted intellectualwho had won a fellowship at Oxford, a Homeric scholar, a poet with a gift forirony and humour, and one of the earliest exponents of the new science ofanthropological mythology; Haggard was less well educated and more seriousminded,he preferred action to ideas, was personally involved in the extension ofBritish rule in Southern Africa,7 and had a close experience of African tribal life.This article sets out to investigate the relationship between these two men, and toassess the extent to which Lang’s classical and anthropological thinking shaped thenarratives of Haggard, especially those set in his imperialistic fantasy of theAfrican continent.

    2011-06-01

    Affective stimuli are increasingly used in emotion research. Typically, stimuli are selected from databases providing affective norms. The validity of these norms is a critical factor with regard to the applicability of the stimuli for emotion research. We therefore probed the validity of the Leipzig Affective Norms for German (LANG) by correlating valence and arousal ratings across different sensory modalities. A sample of 120 words was selected from the LANG database, and auditory recordings of these words were obtained from two professional actors. The auditory stimuli were then rated again for valence and arousal. This cross-modal validation approach yielded very high correlations between auditory and visual ratings (>.95). These data confirm the strong validity of the Leipzig Affective Norms for German and encourage their use in emotion research.

    2012-01-01

    Modern computer programming languages are governed by complex syntactic rules. They are unlike natural languages; they require extensive manual work and a significant amount of learning and practicing for an individual to become skilled at and to write correct programs. Computer programming is a difficult, complicated, unfamiliar, non-automated, and a challenging discipline for everyone; especially, for students, new programmers and end-users. This paper proposes a new programming language and an environment for writing computer applications based on source-code generation. It is mainly a template-driven automatic natural imperative programming language called MyProLang. It harnesses GUI templates to generate proprietary natural language source-code, instead of having computer programmers write the code manually. MyProLang is a blend of five elements. A proprietary natural programming language with unsophisticated grammatical rules and expressive syntax; automation templates that automate the generation of in...

    2014-07-01

    The Peramora Mélange is part of an accretionary complex between the South Portuguese Zone (a fragment of Laurussia) and the Ossa Morena Zone (para-autochthonous Gondwana) and is an expression of the Pangean suture zone in southwestern Iberia. The suture zone is characterized by fault-bounded units of metasedimentary rocks, mélanges, and mafic complexes. Detailed geologic mapping of the Peramora Mélange reveals a complex pattern of imbricated schists and mafic block-in-matrix mélanges. Geochemical signatures of the Pulo do Lobo schist (PDL) are consistent with derivation from both mafic and continental sources. The mafic block-in-matrix mélange displays normal mid-ocean ridge basalt (NMORB) geochemical signature, juvenile Sm-Nd isotopic compositions, and a range of zircon ages similar to those observed in the PDL, suggesting a sedimentary component. Taken together, these data suggest a complex tectonic history characterized by erosion of a NMORB source, mélange formation, and imbrication during underplating occurring during the final stages of continent-continent collision.

Cette synthèse bibliographique concerne principalement les mélanges mécaniques de polymères incompatibles à l'état fondu. Ceux-ci ont une morphologie hétérogène qui dépend des conditions de mise en oeuvre autant que de la nature des constituants. De plus, pour ce type de matériaux, la nature de l'interface joue un rôle déterminant sur la formation de la morphologie hétérogène et donc sur les propriétés du produit final. D'autre part un problème important réside dans la stabilité des mélanges réalisés. L'ajout d'une faible quantité d'agent tensioactif de type copolymère séquencé, ou greffé, ou la modification chimique des constituants (greffage ou réticulation par exemple permet, dans certains cas d'améliorer très sensiblement les propriétés des mélanges en augmentant l'adhérence entre les phases immiscibles.

Users can explore solar image archives, create movies on the fly, and interact with other solar and heliospheric services like the SDO cut-out service and the Virtual Solar Observatory (VSO). In addition to providing a powerful platform for browsing heterogeneous sets of solar data, Helioviewer.org also seeks to be as flexible and extensible as possible, providing access to much its functionality via a simple Application Programming Interface (API). The API can be used to create images and movies from data available on Helioviewer.org, or to embed a simplified version of Helioviewer.org into another website. Recently the Helioviewer.org API was used for two such applications developed by outside interests: an SDO data browser, and a Python library for solar physics data analysis (SunPy). These applications are discussed and examples of API usage are provided. Finally, Helioviewer.org is undergoing continual development with new features being added monthly.

  13. Of moths and men: Theo Lang and the persistence of Richard Goldschmidt's theory of homosexuality, 1916-1960.

    Science.gov (United States)

    Dietrich, M R

    2000-01-01

    Using an analogy between moths and men, in 1916, Richard Goldschmidt proposed that homosexuality was a case of genetic intersexuality. As he strove to create a unified theory of sex determination that would encompass animals ranging from moths to men, Goldschmidt's doubts grew concerning the association of homosexuality with intersexuality until, in 1931, he dropped homosexuality from his theory of intersexuality. Despite Goldschmidt's explicit rejection of his theory of homosexuality, Theo Lang, a researcher in the Genealogical-Demographic Department of the Institute for Psychiatric Research in Munich, revived it, maintained Goldschmidt's association with it, and argued on its behalf in publications from 1936 to 1960. Lang's appropriation of Goldschmidt's theory did not depend on his resolution of the difficulties Goldschmidt had found with his own theory. Lang and Goldschmidt, I argue, had fundamentally different scientific and social commitments that allowed one to reject this theory of homosexuality and the other to accept it.

The major technical challenges with respect to pipeline design in this area are: extreme seabed topography combined with inhomogeneous soil conditions; uncertainties related to current velocities and distribution; high number of spans including some very long spans; deep waters and therefore difficult and costly seabed preparation/span intervention; flowlines with large potential to buckle laterally in combination with free spans. In order to minimise span intervention costs, a major testing campaign and research programme has been conducted in the Ormen Lange project to come up with a design procedure in compliance with the DNV-RP-F105 (DNV, 2002) design philosophy. The improvements in terms of reduced seabed intervention and rock dumping costs are in the order of several 100 MNOKs. The lessons learned and the improved knowledge will also be a great value for other project dealing with similar free span problems. (author)

    Full Text Available Este trabalho estuda a finitude no contexto do envelhecimento por meio do filme A Morte Cansada do cineasta Fritz Lang. Discute a visão do cineasta, especialmente a existência humana, tendo como eixo condutor uma reflexão sobre envelhecimento e morte, questões intrinsecamente ligadas ao tema do sentido da vida, remetendo às discussões sobre a imortalidade da alma e a existência de Deus. Neste filme Lang apresenta a história das três luzes: tentativas de esperança, conflitos sobre o amor, a conquista da vida e a aceitação da morte. A investigação realizada mostra que a arte que se faz através do cinema contribui na compreensão do caráter finito da vida, uma questão complexa na velhice, a constante busca de respostas para as inquietudes do que seja o morrer, o que representa para o velho ser definitivamente um ser finito.

    Middle Eocene to middle Miocene mélange and broken formations are exposed in the coastal outcrops along the west side of the Olympic Peninsula, Washington. A petroleum geochemical assessment of these geologic units has included the investigation of biomarker compounds. A comparison was made of biomarkers in an oil sample from a middle Miocene reservoir penetrated in the Medina No. 1 well with biomarkers in extracts from two samples of middle Eocene Ozette mélange (one sample having a strong petroliferous odor, and the other sample lacking this characteristic odor). Distribution patterns of n-alkanes, tricyclic terpanes, pentacyclic triterpanes, steranes, and diasteranes are remarkably similar in the oil and rock extracts. Biomarker maturity parameters indicate higher maturity in the oil relative to the extracts. The presence of 17α(H)-23,28-bisnorlupane, 18α(H)- and 18β(H)-oleanane, and de-A-lupane and an odd-carbon-number dominance of the n-alkanes in the oil and extracts seems to tie the hydrocarbons to a common source that has a significant terrigenous component.

  18. Validation of the Eddy Viscosity and Lange Wake Models using Measured Wake Flow Characteristics Behind a Large Wind Turbine Rotor

    The wake effects behind wind turbines were investigated by using data from a Met Mast tower and the SCADA (Supervisory Control and Data Acquisition) system for a wind turbine. The results of the wake investigations and predicted values for the velocity deficit based on the eddy viscosity model were compared with the turbulence intensity from the Lange model. As a result, the velocity deficit and turbulence intensity of the wake increased as the free stream wind speed decreased. In addition, the magnitude of the velocity deficit for the center of the wake using the eddy viscosity model was overestimated while the turbulence intensity from the Lange model showed similarities with measured values.

    Reaction rinds between differing lithologies are commonly considered the result of fluid-assisted metasomatic alteration, however, enrichments in relatively fluid-immobile elements such as Cr and Ni seemingly reflect other processes such as volume strain or tectonic mixing. Eleven samples along a 30 cm traverse of an amphibolite grade block and its reaction rind adjacent to ultramafic-rich matrix, show dramatic change in mineral abundance and whole-rock major and trace element and Li isotope composition. Samples of the rind are enriched in whole-rock SiO2, K2O, Rb, Ba, Li, MgO, Cr, Ni, and also Os, Ir and Ru relative to samples of the block core, and are depleted in FeO, Al2O3, TiO2, CaO, and Zr. δ7LiL-SVEC ranges from -3 to +1% and the distribution of Li concentrations and δ7Li is consistent with diffusion on the scale of nearly the entire profile. FeO content of garnets in the rind is lower than that of garnets in the block core, reflecting whole-rock FeO concentrations, and suggesting garnet growth after the depletion in whole-rock FeO. Garnets in the rind show extensive pseudomorphing by decussate chlorite, suggesting post-garnet growth infiltration by H2O-rich fluid. Rind concentrations of Cr, Ni, Zr, Al2O3, TiO2, FeO, and possibly CaO, MgO, Na2O, and Sr can be most simply explained by mechanical mixing of mafic block with mèlange matrix. Such mixing cannot explain the increases in SiO2, K2O, Li, and Ba, and we propose that the concentrations of these elements in the rind reflect element mobility during relatively late-stage fluid infiltration. We propose an early episode of mechanical mixing during which mixing of material derived from the mafic block and mèlange matrix produced rind-like material which then accreted onto the basaltic block. Garnet growth in both the block core and the rind occurred after this mechanical mixing. Fluid infiltration in the rind occurred after peak metamorphism of the block, causing alteration of garnet to chlorite and the

  1. Structural analysis and shape-preferred orientation determination of the mélange facies in the Chañaral mélange, Las Tórtolas Formation, Coastal Cordillera, northern Chile

    2016-04-01

    This study sheds light on the tectonic and structural knowledge of the mélange facies located to the south of Chañaral city, Chile. The Chañaral mélange has been related to an accretionary prism at the western active continental margin of Gondwana. Based on the fossil content, the original turbidite sequence would have been deposited during Devonian to Carboniferous times. The Chañaral mélange is included in the Las Tórtolas Formation, which corresponds to the Paleozoic metasedimentary basement located in the Coastal Range in northern Chile. It consists of a monotonous sequence of more than 90% of interbedded sandstones and shales, with a few limestones, pelagic chert, conglomerates and basic volcanic rocks, metamorphosed to the greenschist facies. In the study area, the Las Tórtolas Formation is divided into two structural domains separated by a major reverse dextral structure, called here the Infieles fault. To the east, the Las Tórtolas Formation is characterized by a brittle-ductile deformation, defined by the original sedimentary contacts in the turbiditic sequence. Besides, thrust faults and associated thrust propagation folds promotes a penetrative axial plane foliation. Mélange facies are located to the west of the Infieles fault. Although lithologies comprising this domain are similar to the rest of the Las Tórtolas Formation, mélange facies (ductile domain) are characterized by the complete disruption of the original architecture of the turbidite succession. The most significant structures in the mélange are the ubiquitous boudinage and pinch and swell structures, asymmetric objects, S-C structures and tight to isoclinal folds. This deformation is partitioned in the Chañaral mélange between linear fabric domains (L), characterized by quartzite blocks with prolate shape in a phyllite matrix with pencil structures, and linear-planar fabric domains (L-S), where quartzite objects show oblate shape and phyllites present a penetrative foliation

    Lange, R; Houran, J

    1997-06-01

    Houran and Lange's psychological model of haunting phenomena predicts that contextual variables alone are sufficient to induce poltergeist-like perceptions. 22 subjects individually visited five areas of a performance theater and were asked to notice the environment. 11 subjects in an informed condition were instructed that the location was haunted, while 11 in the control condition were told that the building was simply under renovation. Subjects' perceptions in both conditions were recorded via Green, et al.'s 1992 experiential questionnaire which contains 10 subscales related to psychological and physiological perceptions. Analysis yielded significantly more intense perceptual experiences on nine of the ten subscales in the informed condition, indicating that demand characteristics alone can stimulate paranormal-type experiences.

    Detailed studies indicate that Kangxian-Pipasi-Nanping tectonic zone is a complicated mélange zone which includes many tectonic slabs of different origins. Ophiolite (MORB-type basalt), oceanic island tholeiite and alkaline basalt have been identified. Moreover, this tectonic mélange zone is eastward connected with the Mianlüe suture zone. The deformation characteristics, consisting components and volcanic rock geochemical features for the Kangxian-Pipasi-Nanping tectonic mélange zone are much similar to those of the Mianlüe suture zone and Deerni ophiolite. Therefore, the Kangxian-Pipasi-Nanping tectonic mélange zone should be the westward extension part of the Mianlüe suture zone. It indicates that the Mianlüe suture zone had extended to the Nanping area.

  3. A search for uniparental disomy associated with Cornelia de Lange syndrome and with spontaneous abortion

    1994-09-01

    Uniparental disomy (UPD) is the inheritance of a pair of homologous chromosomes from one parent with no corresponding homologue from the other, in an individual with an apparently normal karyotype. Polymorphic DNA markers for the appropriate chromosome will therefore lack alleles from the non-contributing parent. There may be pathological consequences of UPD if an imprinted gene(s) resides on the affected chromosome. A number of human developmental disorders of unknown etiology, including Cornelia de Lange syndrome (CdLS) and spontaneous abortion, may be caused by imprinted genes yet to be discovered. There are a number of reports of chromosome 3q rearrangements associated with CdLS, therefore excluding whole-chromosome 3 UPD as a cause in these patients. We are also examining DNA markers for all autosomes in a series of 42 karyotypically normal spontaneous abortions and their parents. To date, no UPD has been observed for chromosomes 3, 17, 20, 21 and 22. Further work is in progress, both here and using the DNA typing facilities at Geneathon, France.

    Brachmann-De Lange syndrome (BDLS, MIM No. 122470) is a well-described genetic syndrome of mental retardation and multiple congenital anomalies, with an estimated birth prevalence of 1/10,000. The authors set out to test the hypothesis that some cases of BDLS are associated with uniparental disomy for chromosome 3, especially for 3q21-qtre. The following DNA polymorphic markers were used to test for uniparental disomy:SST maps on 3q28; GLUT2 on 3q26.1-q26.3; D3S196 on 3q24-q26, D3S1101 on 3p21-cen and D3S1206 on 3q21-q24. The order of these loci in the linkage map of chromosome 3 is pter-D3S1101-cen-D3S1206-D3S196-GLUT2-SST [NIH/CEPH Collaborative Mapping Group, 1992]. All of these polymorphisms are due to dinucleotide repeats and genotypes in the families were obtained as described. In 22 families UPD3q has been excluded. Four families were not informative for the markers used. There were no families with UPD3q. The authors concluded that UPD3q is not associated with most cases of BDLS; however, this study does not exclude the possibility of UPD for a small portion of 3q, that has not been examined with the markers used.

    Full Text Available Climate Change policies are playing an ever-increasing role in global development strategies and their implementation gives rise to often-unforeseen social conflicts and environmental degradations. A landscape approach to analyzing forest-based Climate Change Mitigation policies (CCM and land grabs in the Prey Lang Forest landscape, Cambodia revealed two Korea-Cambodia partnership projects designed to increase forest cover that are juxtaposed in this paper. Case study data revealed a REDD+ project with little negative impact or social conflict in the project area and an Afforestation/Reforestation (A/R project that created both social and ecological conflicts. The study concludes that forest-based CCM policies can reduce conflict through efforts at minimal transformation of local livelihoods, maximal attention to the tenure rights, responsibilities, and authority of citizens, and by improving, not degrading, the project landscapes. The paper presents the circumstances under which these guidelines are sidestepped by the A/R project, and importantly reveals that dramatic forest and livelihood transformation had already affected the community and environment in the REDD+ project site. There are deep contradictions at the heart of climate change policies toward which attention must be given, lest we leave our future generations with nothing but forest islands and castaway communities.

Out of total 1,642 single spore isolates, only 36 single spore isolates were homokaryons and exhibited slow mycelial growth rate (≤2.0 mm/day) and appressed colony morphology. All these SSIs failed to produce pinheads in Petri plates even after 65 days of incubation, whereas the strandy slow growing SSIs along with parent strains were able to form the fructification in petriplates after 30 days. Out of 24, six ISSR primers, exhibited scorable bands. In the ISSR fingerprints, single spore isolates, homokaryons, lacked amplification products at multiple loci; they grow slowly and all of them had appressed types of colony morphology. The study revealed losses of ISSR polymorphic patterns in non-fertile homokaryotic single spore isolates compared to the parental control or fertile heterokaryotic single spore isolates.

    Cornelia de Lange syndrome (CdLS) is a cohesinopathy causing delayed growth and limb deficits. Individuals with CdLS have mild to profound intellectual disability and autistic features. This study characterizes the behavioral phenotype of children with CdLS, focusing on autistic features, maladaptive behaviors, and impact of age. Children with CdLS (5-18 years) were administered normed instruments to characterize autism features (Childhood Autism Rating Scale, CARS), maladaptive behaviors (Aberrant Behavior Checklist), and adaptive skills (Vineland Adaptive Behaviors Scales). CdLS features and severity were rated with Diagnostic Criteria for CdLS. Forty-one children with CdLS (23 females, 18 males) were classified as having "no autism" (n = 7; 17.1%), "mild autism" (n = 17; 41.4%), and "severe autism" (n = 17; 41.4%), using CARS scores. Characteristic items were abnormal emotional response, stereotypies, odd object use, rigidity, lack of verbal communication, and low intellectual functioning. Verbal communication deficits and repetitive behaviors were higher compared to sensory, social cognition, and behavior abnormalities (P ≤ 0.0001). Maladaptive behaviors associated with autism traits were stereotypies (P = 0.003), hyperactivity (P = 0.01), and lethargy (P = 0.03). Activities of daily living were significantly affected; socialization adaptive skills were a relative strength. However, with advancing age, both socialization (P socialization adaptive skills are less affected. Advancing age can worsen communication and socialization deficits relative to neurotypical peers.

    Computational modeling is an important element of systems biology. One of its important applications is modeling complex, dynamical, and biological systems, including viral infections. This type of modeling usually requires close cooperation between biologists and mathematicians. However, such cooperation often faces communication problems because biologists do not have sufficient knowledge to understand mathematical description of the models, and mathematicians do not have sufficient knowledge to define and verify these models. In many areas of systems biology, this problem has already been solved; however, in some of these areas there are still certain problematic aspects. The goal of the presented research was to facilitate this cooperation by designing seminatural formal language for describing viral infection models that will be easy to understand for biologists and easy to use by mathematicians and computer scientists. The ModeLang language was designed in cooperation with biologists and its computer implementation was prepared. Tests proved that it can be successfully used to describe commonly used viral infection models and then to simulate and verify them. As a result, it can make cooperation between biologists and mathematicians modeling viral infections much easier, speeding up computational verification of formulated hypotheses.

    Full Text Available Cornelia de Lange Syndrome (CdLS (also called Bushy Syndrome or Amsterdam dwarfism, is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth, upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Full Text Available The article presents an unofficial discussion that took place between one of the most prominent Polish critics of the late 19th century and Antoni Lange, a raising poet of the 90s, whose work had gained little attention from the older colleague. Mentioned briefly in Chmielowski’s Współczesni poeci polscy in 1895, Lange responded to some of the critic’s fterwards. Chmielowski did not respond to that directly, however, his review of Lange’s volume of poetry published at the time and the will to defend his claims using the adversary’s poetry as a pretext shows that the young poet had succeeded in provoking the respected critic to take defensive position. The two writers, discussing an ongoing ‘crisis’ of poetry, present their own perspectives on the roots of the situation. Chmielowski’s claims from the beginning of the 20th century prove that the dispute, unofficial as it was, was won by Antoni Lange.

  16. Drosophila Nipped-B Mutants Model Cornelia de Lange Syndrome in Growth and Behavior.

    Yaning Wu

    2015-11-01

    Full Text Available Individuals with Cornelia de Lange Syndrome (CdLS display diverse developmental deficits, including slow growth, multiple limb and organ abnormalities, and intellectual disabilities. Severely-affected individuals most often have dominant loss-of-function mutations in the Nipped-B-Like (NIPBL gene, and milder cases often have missense or in-frame deletion mutations in genes encoding subunits of the cohesin complex. Cohesin mediates sister chromatid cohesion to facilitate accurate chromosome segregation, and NIPBL is required for cohesin to bind to chromosomes. Individuals with CdLS, however, do not display overt cohesion or segregation defects. Rather, studies in human cells and model organisms indicate that modest decreases in NIPBL and cohesin activity alter the transcription of many genes that regulate growth and development. Sister chromatid cohesion factors, including the Nipped-B ortholog of NIPBL, are also critical for gene expression and development in Drosophila melanogaster. Here we describe how a modest reduction in Nipped-B activity alters growth and neurological function in Drosophila. These studies reveal that Nipped-B heterozygous mutant Drosophila show reduced growth, learning, and memory, and altered circadian rhythms. Importantly, the growth deficits are not caused by changes in systemic growth controls, but reductions in cell number and size attributable in part to reduced expression of myc (diminutive and other growth control genes. The learning, memory and circadian deficits are accompanied by morphological abnormalities in brain structure. These studies confirm that Drosophila Nipped-B mutants provide a useful model for understanding CdLS, and provide new insights into the origins of birth defects.

    Full Text Available Abstract Background Cornelia de Lange syndrome (CdLS is a dominantly inherited disorder characterized by facial dysmorphism, growth and cognitive impairment, limb malformations and multiple organ involvement. Mutations in NIPBL gene account for about 60% of patients with CdLS. This gene encodes a key regulator of the Cohesin complex, which controls sister chromatid segregation during both mitosis and meiosis. Turner syndrome (TS results from the partial or complete absence of one of the X chromosomes, usually associated with congenital lymphedema, short stature, and gonadal dysgenesis. Case presentation Here we report a four-year-old female with CdLS due to a frameshift mutation in the NIPBL gene (c.1445_1448delGAGA, who also had a tissue-specific mosaic 45,X/46,XX karyotype. The patient showed a severe form of CdLS with craniofacial dysmorphism, pre- and post-natal growth delay, cardiovascular abnormalities, hirsutism and severe psychomotor retardation with behavioural problems. She also presented with minor clinical features consistent with TS, including peripheral lymphedema and webbed neck. The NIPBL mutation was present in the two tissues analysed from different embryonic origins (peripheral blood lymphocytes and oral mucosa epithelial cells. However, the percentage of cells with monosomy X was low and variable in tissues. These findings indicate that, ontogenically, the NIPBL mutation may have appeared before the mosaic monosomy X. Conclusions The coexistence in several patients of these two rare disorders raises the issue of whether there is indeed a cause-effect association. The detailed clinical descriptions indicate predominant CdLS phenotype, although additional TS manifestations may appear in adolescence.

    Neurobehavioral and developmental issues with a broad range of deficits are prominent features of Cornelia de Lange syndrome (CdLS), a disorder due to disruption of the cohesin protein complex. The etiologic relationship of these clinical findings to anatomic abnormalities on neuro-imaging studies has not, however, been established. Anatomic abnormalities in the brain and central nervous system specific to CdLS have been observed, including changes in the white matter, brainstem, and cerebellum. We hypothesize that location and severity of brain abnormalities correlate with clinical phenotype in CdLS, as seen in other developmental disorders. In this study, we retrospectively evaluated brain MRI studies of 15 individuals with CdLS and compared these findings to behavior at the time of the scan. Behavior was assessed using the Aberrant Behavior Checklist (ABC), a validated behavioral assessment tool with several clinical features. Ten of fifteen (67%) of CdLS patients had abnormal findings on brain MRI, including cerebral atrophy, white matter changes, cerebellar hypoplasia, and enlarged ventricles. Other findings included pituitary tumors or cysts, Chiari I malformation and gliosis. Abnormal behavioral scores in more than one behavioral area were seen in all but one patient. All 5 of the 15 (33%) patients with normal structural MRI studies had abnormal ABC scores. All normal ABC scores were noted in only one patient and this was correlated with moderately abnormal MRI changes. Although our cohort is small, our results suggest that abnormal behaviors can exist in individuals with CdLS in the setting of relatively normal structural brain findings. © 2016 Wiley Periodicals, Inc.

  20. Interpretation of tracer tests performed in fractured rock of the Lange Bramke basin, Germany

    Science.gov (United States)

    Maloszewski, Piotr; Herrmann, Andreas; Zuber, Andrzej

    Two multitracer tests performed in one of the major cross-fault zones of the Lange Bramke basin (Harz Mountains, Germany) confirm the dominant role of the fault zone in groundwater flow and solute transport. Tracers having different coefficients of molecular diffusion (deuterium, bromide, uranine, and eosine) yielded breakthrough curves that can only be explained by a model that couples the advective-dispersive transport in the fractures with the molecular diffusion exchange in the matrix. For the scale of the tests (maximum distance of 225m), an approximation was used in which the influence of adjacent fractures is neglected. That model yielded nearly the same rock and transport parameters for each tracer, which means that the single-fracture approximation is acceptable and that matrix diffusion plays an important role. The hydraulic conductivity of the fault zone obtained from the tracer tests is about 1.5×10-2m/s, whereas the regional hydraulic conductivity of the fractured rock mass is about 3×10-7m/s, as estimated from the tritium age and the matrix porosity of about 2%. These values show that the hydraulic conductivity along the fault is several orders of magnitude larger than that of the remaining fractured part of the aquifer, which confirms the dominant role of the fault zones as collectors of water and conductors of fast flow. Résumé Deux multitraçages ont été réalisés dans l'une des zones principales de failles du bassin de Lange Bramke (massif du Harz, Allemagne); les résultats confirment le rôle prédominant de la zone de failles pour l'écoulement souterrain et le transport de soluté. Les traceurs, possédant des coefficients de diffusion différents (deutérium, bromure, uranine et éosine), ont fourni des courbes de restitution qui ne peuvent être expliquées que par un modèle qui associe un transport advectif-dispersif dans les fractures à un échange par diffusion moléculaire dans la matrice.

    U-Pb zircon geochronology, Sr-Nd isotope and bulk-rock geochemistry have been applied to meta-igneous and meta-sedimentary rocks from high-pressure metamorphic mélanges exposed on the Cycladic islands of Tinos, Syros and Andros. Ion microprobe (SHRIMP) U-Pb zircon dating of 7 samples representing meta-igneous blocks (Tinos), a blackwall zone (Tinos) and chlorite-talc schists from block-matrix contacts (Syros and Tinos) yielded Cretaceous ages of c. 80 Ma. Many of the criteria commonly used to distinguish between magmatic or metamorphic zircon genesis (internal structure, Th/U ratio, REE characteristics, Ti-in zircon thermometry, enclosed mineral phases) do not provide unambiguous constraints for the mode of formation. However, a magmatic origin for Cretaceous zircon of meta-gabbros and eclogites is considered likely. Supporting evidence for a previously suggested metamorphic origin for c. 80 Ma zircon in eclogite has not been found. Zircon of the same age occurring in chlorite-talc schists is presumably related to non-magmatic processes. Well-defined Cretaceous age groups clustering at c. 79 Ma also occur in the detrital zircon populations of 2 quartz mica schists representing the mélange matrix on Tinos, and suggest a much later time for sediment accumulation than previously assumed. The importance of c. 57 Ma zircon ages remains unclear, but may record either HP metamorphic processes or a post-57 Ma depositional age. The youngest age group in a third quartz mica schist from Tinos, collected outside the main mélange occurrences, clusters at c. 226-238 Ma. In all clastic metasediments from Tinos, most data points plot along the concordia between c. 300 and 900 Ma; single data points indicate concordant ages of c. 2.5 Ga, 2.3 Ga and 1 Ga, respectively. The youngest 206Pb/ 238U age group that has been recognized in a felsic paragneiss from Andros indicates an age of 163.1 ± 3.9 Ma, and mostly represents overgrowths around zircon with ages in the range from ˜ 272

    Many scientific domains, specifically in the geosciences, rely on physical samples as basic elements for study and experimentation. Samples are collected to analyze properties of natural materials and features that are key to our knowledge of Earth's dynamical systems and evolution, and to preserve a record of our environment over time. Huge volumes of samples have been acquired over decades or even centuries and stored in a large number and variety of institutions including museums, universities and colleges, state geological surveys, federal agencies, and industry. All of these collections represent highly valuable, often irreplaceable records of nature that need to be accessible so that they can be re-used in future research and for educational purposes. Many sample repositories are keen to use cyberinfrastructure capabilities to enhance access to their collections on the internet and to support and streamline collection management (accessioning of new samples, labeling, handling sample requests, etc.), but encounter substantial challenges and barriers to integrate digital sample management into their daily routine. They lack the resources (staff, funding) and infrastructure (hardware, software, IT support) to develop and operate web-enabled databases, to migrate analog sample records into digital data management systems, and to transfer paper- or spreadsheet-based workflows to electronic systems. Use of commercial software is often not an option as it incurs high costs for licenses, requires IT expertise for installation and maintenance, and often does not match the needs of the smaller repositories, being designed for large museums or different types of collections (art, archeological, biological). Geosamples.org is an alliance of sample repositories (academic, US federal and state surveys, industry) and data facilities that aims to develop a cyberinfrastructure that will dramatically advance access to physical samples for the research community, government

    Many school districts within the United States continue to seek new ways of engaging students within Science, Technology, Engineering, and Mathematics (STEM) disciplines. SAGANet.org, a web-based 501c3 Astrobiology outreach initiative, works with a number of schools, partnering K-12 students and their families with professional scientist mentors from around the world to teach and inspire students using virtual technology platforms. Current programs include two mentoring partnerships: pairing scientist-mentors with at-risk youth at the Pittsburg Community School in Pittsburg CA, and pairing scientist-mentors with families from the Kyrene del Cielo Elementary School in Chandler AZ. These programs represent two very different models for utilizing the virtual media platform provided by SAGANet.org to engage K-12 students and their families in STEM. For the former, scientists mentor the students of the Pittsburg School as part of the formal in-class curriculum. For the latter, scientists work with K-5 students and their families through Cielo's Science & Engineering Discovery Room to develop a science project as part of an informal learning experience that is independent of the formal curriculum. In this presentation, we (1) discuss the challenges and successes of engaging these two distinct audiences through virtual media, (2) present the results of how these two very-different mentoring partnership impact K-12 students science self-efficacy, interest in science, and STEM career awareness, and (3) share the impact of the mentoring experience on the mentor's confidence and self-efficacy with communicating science to the public.

    The data.oceandrilling.org web application applies Linked Open Data (LOD) patterns to expose Deep Sea Drilling Project (DSDP), Ocean Drilling Program (ODP) and Integrated Ocean Drilling Program (IODP) data. Ocean drilling data is represented in a rich range of data formats: high resolution images, file based data sets and sample based data. This richness of data types has been well met by semantic approaches and will be demonstrated. Data has been extracted from CSV, HTML and RDBMS through custom software and existing packages for loading into a SPARQL 1.1 compliant triple store. Practices have been developed to streamline the maintenance of the RDF graphs and properly expose them using LOD approaches like VoID and HTML embedded structured data. Custom and existing vocabularies are used to allow semantic relations between resources. Use of the W3c draft RDF Data Cube Vocabulary and other approaches for encoding time scales, taxonomic fossil data and other graphs will be shown. A software layer written in Google Go mediates the RDF to web pipeline. The approach used is general and can be applied to other similar environments like node.js or Python Twisted. To facilitate communication user interface software libraries such as D3 and packages such as S2S and LodLive have been used. Additionally OpenSearch API's, structured data in HTML and SPARQL endpoints provide various access methods for applications. The data.oceandrilling.org is not viewed as a web site but as an application that communicate with a range of clients. This approach helps guide the development more along software practices than along web site authoring approaches.

    The Indus-Yarlung Suture Zone (IYSZ) is the boundary between rocks of Indian and Asian affinity. From north to south in southern Tibet, it exposes the preserved Asian forearc, ophiolitic rocks, tectonic mélanges, and Tethyan Himalayan strata of Indian affinity. The mélange has long been considered the accretionary prism corresponding to the ophiolite to the north which obducted onto the Indian margin prior to India-Asia collision. An outstanding issue is whether the ophiolitic rocks and mélanges were (1) obducted onto the northern margin of India or (2) associated with the Cordilleran-style southern margin of Asia, prior to India - Asia collision. Resolving this issue is fundamental to understanding the precollisional tectonic framework of the Neo-Tethyan realm, interpreting the timing of initial continental collision from detrital records, and locating the suture. We conducted geologic mapping and U/Pb detrital zircon provenance studies of the blocks and matrix of the mélanges and of Tethyan Himalayan units to the south at two localities: near Lhatse, which is ~140 km north of Mt. Everest and near Lopu Kangri, ~300 km along strike to the west. Near Lhatse the mélange is composed of a mudstone matrix with blocks of basalt, chert, mudstone, metabasite, limestone, and sandstone. The majority of the blocks are deep-water facies or consistent with oceanic crust, supporting the interpretation that the mélange is an accretionary complex formed by oceanic subduction. A south-dipping fault ~9 km north of Lhatse separates the mélange to the north from a continuous sequence of sandstone, shale, and minor limestone to the south. Previous work along strike suggests that this sequence, which has been previously identified as Tethyan affinity, contains Asian affinity detrital zircon populations. Near Lopu Kangri, the mélange is similar to that exposed in Lhatse. Over a distance of ~10 km to the southwest, blocks gradually increase in size to encompass ~2 km x ~10 km

    With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange) Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent taste, with its antioxidant and anti-hypoxic abilities unknown. In this work, the antioxidant potential of its methanolic, 55% ethanolic, aqueous extracts and crude polysaccharide was evaluated in different systems. The results showed that polysaccharide was the most effective in scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals, metal chelating activity and reducing power, with EC50 values of 0.02, 2.79, 1.29, and 1.82 mg/mL, respectively. Therefore, we further studied the anti-hypoxic activity of crude polysaccharide. The results turned out that polysaccharide (300 mg/kg) prolonged the survival time, decreased the blood urea nitrogen and lactic acid content as well as increased the liver glycogen significantly, compared with the blank control and the commercialized product Hongjingtian (p Agaricus bisporus (Lange) Sing. Chaidam had strong potential to be exploited as an effective natural functional food to relieve oxidative and hypoxia stresses.

    Comparative genomics provides the means to demarcate functional regions in anonymous DNA sequences. The successful application of this method to identifying novel genes is currently shifting to deciphering the noncoding encryption of gene regulation across genomes. To facilitate the use of comparative genomics to practical applications in genetics and genomics we have developed several analytical and visualization tools for the analysis of arbitrary sequences and whole genomes. These tools include two alignment tools: zPicture and Mulan; a phylogenetic shadowing tool: eShadow for identifying lineage- and species-specific functional elements; two evolutionary conserved transcription factor analysis tools: rVista and multiTF; a tool for extracting cis-regulatory modules governing the expression of co-regulated genes, CREME; and a dynamic portal to multiple vertebrate and invertebrate genome alignments, the ECR Browser. Here we briefly describe each one of these tools and provide specific examples on their practical applications. All the tools are publicly available at the http://www.dcode.org/ web site.

    Full Text Available BioCyc.org is a genome and metabolic pathway web portal covering 5500 organisms, including Homo sapiens, Arabidopsis thaliana, Saccharomyces cerevisiae and Escherichia coli. These organism-specific databases have undergone variable degrees of curation. The EcoCyc (Escherichia coli Encyclopedia database is the most highly curated; its contents have been derived from 27,000 publications. The MetaCyc (Metabolic Encyclopedia database within BioCyc is a “universal” metabolic database that describes pathways, reactions, enzymes and metabolites from all domains of life. Metabolic pathways provide an organizing framework for analyzing metabolomics data, and the BioCyc website provides computational operations for metabolomics data that include metabolite search and translation of metabolite identifiers across multiple metabolite databases. The site allows researchers to store and manipulate metabolite lists using a facility called SmartTables, which supports metabolite enrichment analysis. That analysis operation identifies metabolite sets that are statistically over-represented for the substrates of specific metabolic pathways. BioCyc also enables visualization of metabolomics data on individual pathway diagrams and on the organism-specific metabolic map diagrams that are available for every BioCyc organism. Most of these operations are available both interactively and as programmatic web services.

    The Exoplanet Orbit Database (EOD) compiles orbital, transit, host star, and other parameters of robustly detected exoplanets reported in the peer-reviewed literature. The EOD can be navigated through the Exoplanet Data Explorer (EDE) Plotter and Table, available on the World Wide Web at exoplanets.org. The EOD contains data for 1492 confirmed exoplanets as of July 2014. The EOD descends from a table in Butler et al. (2002) and the Catalog of Nearby Exoplanets (Butler et al. 2006), and the first complete documentation for the EOD and the EDE was presented in Wright et al. (2011). In this work, we describe our work since then. We have expanded the scope of the EOD to include secondary eclipse parameters, asymmetric uncertainties, and expanded the EDE to include the sample of over 3000 Kepler Objects of Interest (KOIs), and other real planets without good orbital parameters (such as many of those detected by microlensing and imaging).

    Over the last decade, technological advancements have substantially decreased the cost and time of obtaining large amounts of sequencing data. Paired with the exponentially increased computing power, individual labs are now able to sequence genomes or transcriptomes to investigate biological questions of interest. This has led to a significant increase in available sequence data. Although the bulk of data published in articles are stored in public sequence databases, very often, only raw sequencing data are available; miscellaneous data such as assembled transcriptomes, genome annotations etc. are not easily obtainable through the same means. Here, we introduce our website (http://reefgenomics.org) that aims to centralize genomic and transcriptomic data from marine organisms. Besides providing convenient means to download sequences, we provide (where applicable) a genome browser to explore available genomic features, and a BLAST interface to search through the hosted sequences. Through the interface, multiple datasets can be queried simultaneously, allowing for the retrieval of matching sequences from organisms of interest. The minimalistic, no-frills interface reduces visual clutter, making it convenient for end-users to search and explore processed sequence data.

    Available biomedical ontologies and knowledge bases currently lack formal and standards-based interconnections between disease, disease vector, and drug treatment vocabularies. The PNNL Medical Linked Dataset (PNNL-MLD) addresses this gap. This paper describes the PNNL-MLD, which provides a unified vocabulary and dataset of drug, disease, side effect, and vector transmission background information. Currently, the PNNL-MLD combines and curates data from the following research projects: DrugBank, DailyMed, Diseasome, DisGeNet, Wikipedia Infobox, Sider, and PharmGKB. The main outcomes of this effort are a dataset aligned to Schema.org, including a parsing framework, and extensible hooks ready for integration with selected medical ontologies. The PNNL-MLD enables researchers more quickly and easily to query distinct datasets. Future extensions to the PNNL-MLD will include Traditional Chinese Medicine, broader interlinks across genetic structures, a larger thesaurus of synonyms and hypernyms, explicit coding of diseases and drugs across research systems, and incorporating vector-borne transmission vocabularies.

    Full Text Available In order to identify new ways to prevent, diagnose and treat diseases, biobanks systematically collect samples of human tissues and population-wide data on health and lifestyle. Efficient access to population biobank data and to biomaterial is crucial for development and marketing of new pharmaceutical products, especially in the area of personalised medicine. However, such access is hindered by legal and ethical constraints, and by the huge semantic diversity across different biobanks. To address these challenges, we have developed SAIL, a sophisticated metaportal for biobank data annotation across different collections and repositories, harmonised to allow cross-biobank searchability, while preserving the anonymity and privacy of the underlying data such that legal and ethical requirements are met. We describe the technological architecture and design of SAIL that allows us to meet these pressing challenges, and give an overview of the current functionality of the application. SAIL is available online at sail.simbioms.org, and it currently contains around 200 000 samples from 14 collections.

    It is a major challenge to bring science and technology to the public at large and more particular to young people. This is even more true for marine sciences, due to the very nature of the study field and the fact that the underwater world is difficult to experience and communicate. Therefore it is not surprising that in Europe there are only few examples of marine educational projects that try to go beyond the ‘observe and describe' approach. In 2004 SHE Consultancy, the Flanders Marine Institute VLIZ and DAB Vloot developed a first Belgian e-learning programme dedicated to oceans and seas, with the support of the Flemish government ("Action plan Science Communication"). This programme ‘Expedition Zeeleeuw' (www.expeditiezeeleeuw.be), ran from 2005 till 2007 and challenged some 3000 Flemish students of 16-18 years old all over Flanders to find creative solutions for 10 major marine issues at the Belgian coast. The class that could convince the jury to have discovered the most creative and intelligent solutions, wan a one-week scientific expedition at sea on board the vessel Zeeleeuw. As a successor to ‘Expedition Zeeleeuw', a new e-learning project on marine science was developed in 2007: ‘Planeet Zee' i.e. ‘Planet Ocean' (www.planeetzee.org; info via info@planeetzee.org + demo-site in English available at www.planetocean.eu). The new marine and coastal e-learning project is presented as a virtual sailing trip on the Atlantic Ocean. It follows the adventures of two youngsters "borrowing" the yacht of their father and getting into trouble on the open ocean. On this journey they face 21 problems (eg. out of food, drinking water or fuel, fear for whales, Bermuda triangle, tsunami's etc… ), each of them introduced by a short movie clip. When they realize they can not solve the problem, they ask for radio help and - what a surprise! - get interesting answers from the Zeeleeuw research vessel and its 21 marine scientists on board, that appears to be in the

    Full Text Available The ability to transmit, organize, and query information digitally has brought with it the challenge of how to best use this power to facilitate scientific inquiry. Today, few information systems are able to provide detailed answers to complex questions about neuroscience that account for multiple spatial scales, and which cross the boundaries of diverse parts of the nervous system such as molecules, cellular parts, cells, circuits, systems and tissues. As a result, investigators still primarily seek answers to their questions in an increasingly densely populated collection of articles in the literature, each of which must be digested individually. If it were easier to search a knowledge base that was structured to answer neuroscience questions, such a system would enable questions to be answered in seconds that would otherwise require hours of literature review.In this article, we describe NeuroLex.org, a wiki-based website and knowledge management system. Its goal is to bring neurobiological knowledge into a framework that allows neuroscientists to review the concepts of neuroscience, with an emphasis on multiscale descriptions of the parts of nervous systems, aggregate their understanding with that of other scientists, link them to data sources and descriptions of important concepts in neuroscience, and expose parts that are still controversial or missing. To date, the site is tracking ~25,000 unique neuroanatomical parts and concepts in neurobiology spanning experimental techniques, behavioral paradigms, anatomical nomenclature, genes, proteins and molecules.

  1. Unraveling the polymetamorphic history of garnet-bearing metabasites: Insights from the North Motagua Mélange (Guatemala Suture Zone)

    2014-12-01

    The Guatemala Suture Zone is the fault-bound region in central Guatemala that contains the present North American-Caribbean plate boundary. This major composite geotectonic unit contains a variety of ophiolites, serpentinite mélanges, and metavolcano-sedimentary sequences along with high-grade schists, gneisses, low-grade metasediments and metagranites thrusted north and south of the active Motagua fault system (MFS). The North Motagua Mélange (NMM) outcrops north of the MFS and testifies the emplacement of exhumed subduction assemblages along a collisional tectonic setting. The NMM is composed of a serpentinite-matrix mélange that contains blocks of metabasites (subgreenschist facies metabasalt, grt-blueschist, eclogite, grt-amphibolite), vein-related rocks (jadeitite, omphacitite, albitite, mica-rock), and metatrondhjemites. Our new detailed petrographic and thermobarometric study on the garnet-bearing metabasites reveals a complex polymetamorphic history with multiple tectonic events. Eclogites show a classical clockwise PT path composed of (a) prograde blueschist/eclogite facies within garnet cores, (b) eclogite facies metamorphic peak at ~1.7 GPa and 620°C, (c) post-peak blueschist facies, (d) amphibolite facies overprint, and (e) late stage greenschist facies. Two types of garnet amphibolite blocks can be found, the first consist of (a) a relict eclogite facies peak at ~1.3 GPa and 550°C only preserved within anhedral garnet cores, and (b) surrounded by a post-peak amphibolite facies. In contrast, the second type displays a prograde amphibolite facies at 0.6-1.1 GPa and 400-650°C. The eclogites metamorphic peak suggests formation in a normal subduction zone at ~60 km depth, a subsequent exhumation to the middle section of the subduction channel (~35 km), and a later metamorphic reworking at lower P and higher T before its final exhumation. The first type of garnet amphibolite shows a similar trajectory as the eclogites but at warmer conditions. In

    Orogenic wedges locally present chaotic tectonostratigraphic units that contain exotic blocks of various size, origin, age and lithology, embedded in a sedimentary matrix. The occurrence of ophiolitic blocks, sometimes huge, in such "mélanges" raises questions on (i) the mechanisms responsible for the incorporation of oceanic basement rocks into an accretionary wedge and (ii) the mechanisms allowing exhumation and redeposition of these exotic elements in "mélanges" during wedge growth. To address these questions, we present the results of a series of analogue experiments performed to characterize the processes and parameters responsible for accretion, exhumation and tectonosedimentary reworking of oceanic basement lithospheric fragments in an accretionary wedge. The experimental setup is designed to simulate the interaction between tectonics, erosion and sedimentation. Different configurations are applied to study the impact of various parameters, such as irregular oceanic floor due to structural inheritance, or the presence of layers with contrasted rheology that can affect deformation partitioning in the wedge (frontal accretion vs basal accretion) influencing its growth. Image correlation technique allows extracting instantaneous velocity field, and tracking of passive particles. By retrieving the particle paths determined from models, the pressure-temperature path of mélange units or elementary blocks can be discussed. The experimental results are then compared with observations from ophiolite-bearing mélanges in Taiwan (Lichi and Kenting mélanges) and Raman spectroscopy of carbonaceous material (RSCM) Thermometry data on rocks from the northern Apennines (Casanova mélange). A geological scenario is proposed following basic observations. The tectonic evolution of the retroside of doubly vergent accretionary wedges is mainly controlled by backthrusting and backfolding. The retro wedge is characterized by steep slopes that are prone to gravitational

    NifA in Azospirillum brasilense plays a key role in regulating the synthesis of nitrogenase in response to ammonia and oxygen available. Recently,our laboratory has identified four clones, whose gene prodcuts interact with NifA, from A. brasilense Sp7genomic libraries by using the yeast two-hybrid system with NifA as bait. We are interested in clone S35,one of the four clones, because it contains a PAS-domain coding region. The entire open reading frame (ORF) for the PAS domain-containing protein was isolated and designated as org35 here. org35gene is 2211-bp long and encodes a protein of 736aa with a predicted molecular weight of about 78.4 kD.The predicted amino acid sequence of org35 has similarity to some two-component sensor kinase/response regulator hybrids of bacteria. Structural analyses showed that Org35 comprises at least three discrete conserved domains: the N-terminal PAS, the central histidine protein kinase (HPK) and the C-terminal response regulator (RR). The PAS domain of the deduced Org35 protein was found to interact directly with NifA, but the central HPK and the C-terminal RR domains of Org35 were not. These results indicated that interaction between NifA and Org35 was mediated by PAS domain.

    2015-10-01

    Citizen science projects have the potential to advance science by increasing the volume and variety of data, as well as innovation. Yet this potential has not been fully realized, in part because citizen science data are typically not widely shared and reused. To address this and related challenges, we built CitSci.org (see www.citsci.org), a customizable platform that allows users to collect and generate diverse datasets. We hope that CitSci.org will ultimately increase discoverability and confidence in citizen science observations, encouraging scientists to use such data in their own scientific research.

  18. Sandstone provenance and tectonic evolution of the Xiukang Mélange from Neotethyan subduction to India-Asia collision (Yarlung-Zangbo suture, south Tibet)

    2016-04-01

    The Xiukang Mélange of the Yarlung-Zangbo suture zone in south Tibet documents low efficiency of accretion along the southern active margin of Asia during Cretaceous Neotethyan subduction, followed by final development during the early Paleogene stages of the India-Asia collision. Here we investigate four transverses in the Xigaze area (Jiding, Cuola Pass, Riwuqi and Saga), inquiry the composition in each transverse, and present integrated petrologic, U-Pb detrital-zircon geochronology and Hf isotope data on sandstone blocks. In fault contact with the Yarlung-Zangbo Ophiolite to the north and the Tethyan Himalaya to the south, the Xiukang mélange can be divided into three types: serpentinite-matrix mélange composed by broken Yarlung-Zangbo Ophiolite, thrust-sheets consisting mainly chert, quartzose or limestone sheets(>100m) with little intervening marix, and mudstone-matrix mélange displaying typical blocks-in-matrix texture. While serpentinite-matrix mélange is exposed adjacent to the ophiolite, distributions of thrust-sheets and blocks in mudstone-matrix mélange show along-strike diversities. For example, Jiding transverse is dominant by chert sheets and basalt blocks with scarcely sandstone blocks, while Cuola Pass and Saga transverses expose large amounts of limestone/quartzarenite sheets in the north and volcaniclastic blocks in the south. However, turbidite sheets and volcaniclastic blocks are outcropped in the north Riwuqi transverse with quartzarenite blocks preserved in the south. Three groups of sandstone blocks/sheets with different provenance and depositional setting are distinguished by their petrographic, geochronological and isotopic fingerprints. Sheets of turbiditic quartzarenite originally sourced from the Indian continent were deposited in pre-Cretaceous time on the northernmost edge of the Indian passive margin and eventually involved into the mélange at the early stage of the India-Asia collision. Two distinct groups of volcaniclastic

    The geology of the NE Hungarian Darnó Unit is rather complicated, as it is composed mostly of a Jurassic accretionary mélange complex, according to the most recent investigations. The magmatic and sedimentary rock blocks of the mélange represent products of different evolutionary stages of the Neotethys; including Permian and Triassic sedimentary rocks of marine rifting related origin, Triassic pillow basalt of advanced rifting related origin and Jurassic pillow basalt originated in back-arc-basin environment. This small unit contains a copper-gold occurrence in the Permian marly-clayey limestone, an iron enrichment in the Triassic sedimentary succession, a copper-silver ore occurrence in Triassic pillow basalts and a copper ore indication, occurring both in the Triassic and Jurassic pillow basalts. The present study deals with the Cu(-Ag) occurrence in the Triassic basalt and the Fe occurrence in the Triassic sedimentary succession. The former shows significant similarities with the Michigan-type mineralizations, while the latter has typical characteristics of the Fe-SEDEX deposits. All the above localities fit well into the new geological model of the investigated area. The mineralizations represent the different evolutionary stages of the Neotethyan rifting and an epigenetic, Alpine metamorphism-related process and their recent, spatially close position is the result of the accretionary mélange formation. Thus, the Darnó Unit represents a perfect natural laboratory for studying and understanding the characteristic features of several different rifting related ore forming processes.

    Full Text Available Systemic lupus erythematosus (SLE is a chronic autoimmune disease that leads to severe multiorgan damage. Lang Chuang Fang (LCF is a Chinese herbal medicine that is clinically prescribed for treating SLE. In this study, we examined the therapeutic effects of LCF granule on lupus-prone MRL/lpr mice. Female mice were randomly separated into six groups, and LCF treatment groups received LCF granule at the dosage of 0.97 g/kg/d, 1.95 g/kg/d, and 3.90 g/kg/d, respectively. Here, we found that, compared to the MRL/lpr mice, both the spleen coefficient and thymus coefficient were reduced in the LCF granule-treated mice. There was a marked downregulation in CRP and anti-dsDNA autoantibody and an evident upregulation of CH50 in LCF granule-treated mice. LCF granule treatment also obviously reduced the proteinuria, BUN, and SCr levels in MRL/lpr mice at the dosage of 0.97 g/kg/d, 1.95 g/kg/d, and 3.90 g/kg/d, indicating that LCF granule alleviated the renal injury of MRL/lpr mice. Furthermore, LCF granule decreased p65 NF-κB levels and increased Sirt1 and Nrf2 levels in the kidney tissues of MRL/lpr mice, which might elucidate the beneficial effects of LCF on lupus nephritis. In conclusion, this study demonstrates that LCF granule has therapeutic effects on lupus-prone MRL/lpr mice.

    There is an abundance of information in the literature on patient experiences with Internet support groups (ISGs). However, studies exploring these experiences in a rare disease population are scarce, even though these families are often at a disadvantage for resources, reliable information, and support. The aim of the current study was to explore the experiences with ISGs for parents of children with Cornelia de Lange syndrome (CdLS), a rare genetic diagnosis, in order to better understand the impact on emotional support and their child's medical care. Focus groups were conducted to inform the design of a large-scale internet survey. The survey asked parents closed- and open-ended questions regarding experiences with ISGs, with a focus on the psychosocial, medical, and logistical aspects. The survey found that 141/170 (82.6%) respondents have visited an Internet-based support group to find support or information about their child's CdLS diagnosis. The majority of respondents (71.7%) reported that ISGs have been helpful in finding emotional support, with the most common areas impacted as a result of ISG participation being behavior toward their children and family dynamic. Regarding medical care, most respondents (63.9%) reported that ISGs have been helpful in finding medical information and support, with the most commonly impacted areas of their child's care including day-to-day management, diet, therapy interventions, and healthcare providers. These findings provide a greater understanding of the role of Internet networking in healthcare and may inform future approaches to medical care and psychosocial support for rare, complex genetic diagnoses. © 2016 Wiley Periodicals, Inc.

Since different libraries were cataloging articles on their own, the goal was to merge existing collections. As of November 2010 the database bibnet.org contains 45,000 article references from 400 journals. The records origin in the first place from the Rudolfinerhaus in Vienna and the Swiss Pro Senectute library, dating back till 1979. Additional records are beeing catalogued by participating libraries. Each participating library is responsible for an assigned set of journals. The project was built using exclusively Open Source components. Vufind as a discovery layer, KOHA as cataloguing system for those libraries without a capable ILS, Drupal as content management system and Doctor-Doc as linkresolver, ILL system and through its DAIA interface as knowledge database to indicate print holdings availability for the participating libraries.bibnet.org shows the potential libraries can have if they start to cooperate.

  7. lightsources.org: An Internet Site for Light SourceCommunication

    2004-10-04

    Research at the world's accelerator- (storage-ring and linac) based light sources is one of the most dynamic and rapidly growing fields of science. It frequently results in direct benefits to society, thereby demonstrating the value of the research with very concrete examples, but this is not widely understood or appreciated outside of the immediate user community. Our growing group of light source communicators from facilities in Europe, Asia, and the Americas, inspired by the Interactions.org Web site created by high-energy (elementary-particle)physics communicators, concluded that a light source community Web site (lightsources.org) would be the best tool for establishing effective collaboration between the communications offices of the world's light sources and to maximize the impact of our efforts. We envision lightsources.org to serve as a one-stop-shopping site for information about all aspects of light sources and the research they make possible. Audiences to be served include science communicators, the press, policymakers, the light source community, the wider scientific community, the science-interested public, and students and educators. Our proposal has been sent to the world's light source facility directors by J. Murray Gibson (APS) and William G. Stirling (ESRF). As a result,light sources.org is now being supported by a growing list of facilities from Europe, North America, and Asia. We hope to launch lightsources.org before the end of 2004.

    Many writers and researchers are reluctant to publish online for fear that their work will be plagiarized and used without attribution elsewhere. For example, junior or freelance researchers may worry that their ideas will be 'stolen' and published under the name of professional or senior researchers; and that then it could be hard to convince people that in fact the idea had originated elsewhere. However, if this happens, plagiarism may be objectively proven by a service called the Internet Archive Wayback Machine (archive.org). Archive.org permits clarification of the issue of dates--and allows the reader to draw their own conclusions about authorship, whether charitable or otherwise. In sum, archive.org is a little known, freely available and potentially very useful mechanism for defending intellectual property rights.

    Full Text Available This work reviews recent progress in the application of continuous thermodynamics towards calculation of phase equilibria in natural-gas mixtures. In such mixtures, there may be too many components to identify each component individually. Continuous thermodynamics provides a theoretical framework for representing the composition of a portion of the natural-gas mixture by a continuous distribution function. Advances in continuous thermodynamics are discussed in three areas :(1 Characterization and representation of composition in a many-component mixture(2 Development and application of molecular-thermodynamic models for continuous mixtures, and(3 Implementation of efficient numerical techniques for solving material-balance and phase-equilibrium equations. While continuous thermodynamics provides a useful tool for calculation of phase equilibria in natural-gas mixtures, successful implementation requires better chemical-analytical characterization methods. Further, improved semi-theoretical techniques must be developed to relate experimental characterization information to physically significant parameters in molecular-thermodynamic models. Ce travail examine les récents développements de l'application de la thermodynamique continue au calcul des équilibres de phases de mélanges de gaz naturel. Dans ces mélanges, les composants sont souvent en trop grand nombre pour qu'on puisse les identifier individuellement.

  17. Permian Radiolarians from the A’nyemaqen Mélange Zone in the Huashixia Area of Madoi County, Qinghai Province, Western China, and Their Implications on Regional Tectonism

    The Huashixia area in the Madoi County, Qinghai Province, western China is one of the most important areas for the studies of the formation and evolution of the A’nyemaqen mélange zone due to the well exposed, relatively complete tectonostratigraphic successions. However, the timing and evolu-tionary process of the A’nyemaqen paleo-ocean has long been poorly understood. Recently, we obtained abundant radiolarians from the siliceous rocks of the Maerzheng Formation of this mélange zone in Huashixia. Total 19 species in 10 radiolarian genera have been identified. They belong mainly to the Al-baillellaria, Spumellaria, Entactinaria, and Latentifistularia. Four radiolarian assemblage zones are es-tablished, including: thePseudoalbaillella rhombothoracata,Pseudoalbaillella scalprata,Ruzhencevispongus uralicus,andFollicucullus bipartitus-Follicucullussp. cf.F. ventricosus zones. Radiolarian faunal correla-tions suggest a late Artinskian–early Kungurian age and late Capitanian–early Wuchiapingian age for the first two zones from the lower part and the last two zones from the upper parts of the Maerzheng Forma-tion, respectively. All radiolarians are typical of deep water elements living in deep oceans in low latitudes during the Permian. Previously, the radiolarians of Early Carboniferous to Early Permian age and fusu-linids of Early–Middle Permian age have also been reported from the A’nyemaqen mélange successions. The combination of the newly found radiolarians with the previously reported faunal and microfloral as-semblages as well as radiometric ages obtained from the same stratigraphic units indicates that the A’nyemaqen paleo-ocean may have opened initially during the Early Carboniferous, expanded from the Early–Middle Permian, reached its acme in the early Late Permian, shrunk during the latest Permian to Early Triassic, and eventually was closed in the Middle Triassic.

    Full Text Available O mercado de produtos orgânicos vem crescendo graças à preocupação de consumidores com uma alimentação mais saudável e às pressões do mercado para utilização de meios de produção mais sustentáveis. No Brasil, os produtos orgânicos também se configuram como uma tendência. O presente artigo visa identificar os fatores que influenciam o consumo desses produtos em Ribeirão Preto, São Paulo. Para tanto, foca sua análise nos consumidores de produtos orgânicos que optam pelo supermercado como ponto de venda. Empregou-se dois métodos de pesquisa. No primeiro, utilizou-se a pesquisa exploratória e, no segundo, a pesquisa descritiva, mais especificamente o survey. A análise estatística dos dados utilizou a técnica de análise fatorial. Os resultados mostraram que os fatores que levam ao consumo de produtos orgânicos são egocêntricos. Além disso, verificou-se que os consumidores sentem que existem barreiras comerciais que dificultam a compra desses produtos. DOI: 10.5585/remark.v8i1.2131

    The in vitro and in vivo pharmacology of two glycine transporter-1 (GlyT1) inhibitors, N[3-(4'-fluorophenyl)-3-(4'-phenylphenoxy)-propyl]sarcosine (NFPS) and R,S-(+/-)N-methyl-N-[(4-trifluoromethyl)phenoxy]-3-phenyl-propylglycine (Org 24461), was studied. NFPS and Org 24461 inhibited the uptake of [3H]glycine in hippocampal synaptosomal preparation with IC(50) values of 0.022 and 2.5 microM. Neither NFPS nor Org 24461 (0.1 microM) showed significant binding to alpha-1, alpha-2, and beta-adrenoceptors, D(1) and D(2) dopamine receptors, and 5-HT(1A) and 5-HT(2A) serotonin receptors in membranes prepared from rat brain or to cloned 5-HT(6) and 5-HT(7) receptors. At 10 microM concentrations, binding affinity was measured for NFPS to 5-HT(2A) and 5-HT(2C) serotonin receptors and alpha-2 adrenoceptors and for NFPS and Org 24461 to 5-HT(7) serotonin receptors. Glycine (0.1 mM) and sarcosine (5 mM) increased [3H]glycine efflux from superfused rat hippocampal slices preloaded with [3H]glycine. NFPS and Org 24461 (0.1 mM) did not influence [3H]glycine efflux, however, they inhibited glycine-induced [3H]glycine release. These findings indicate that NFPS and Org 24461 selectively inhibit glycine uptake without being substrates of the transporter protein. Several antipsychotic tests were used to characterize antipsychotic effects of NFPS and Org 24461 in vivo. These compounds did not alter apomorphine-induced climbing and stereotypy in a dose of 10 mg/kg p.o. in mice and did not induce catalepsy in a dose of 10 mg/kg i.p. in rats. The ID(50) values of NFPS were 21.4 mg/kg and higher than 30 mg/kg i.p. for inhibition of phencyclidine (PCP)- and D-amphetamine-induced hypermotility in mice and these values were 2.5 and 8.6 mg/kg i.p. for Org 24461. NFPS and Org 24461 did not exhibit anxiolytic effects in light-dark test in mice, in the meta-chlorophenylpiperazine (mCPP)-induced anxiety test (minimal effective dose or MED was higher than 3 mg/kg i.p.) and in the Vogel conflict

    2016-08-01

    This contribution provides an overview of Paleomagnetism.org, an open-source, multi-platform online environment for paleomagnetic data analysis. Paleomagnetism.org provides an interactive environment where paleomagnetic data can be interpreted, evaluated, visualized, and exported. The Paleomagnetism.org application is split in to an interpretation portal, a statistics portal, and a portal for miscellaneous paleomagnetic tools. In the interpretation portal, principle component analysis can be performed on visualized demagnetization diagrams. Interpreted directions and great circles can be combined to find great circle solutions. These directions can be used in the statistics portal, or exported as data and figures. The tools in the statistics portal cover standard Fisher statistics for directions and VGPs, including other statistical parameters used as reliability criteria. Other available tools include an eigenvector approach foldtest, two reversal test including a Monte Carlo simulation on mean directions, and a coordinate bootstrap on the original data. An implementation is included for the detection and correction of inclination shallowing in sediments following TK03.GAD. Finally we provide a module to visualize VGPs and expected paleolatitudes, declinations, and inclinations relative to widely used global apparent polar wander path models in coordinates of major continent-bearing plates. The tools in the miscellaneous portal include a net tectonic rotation (NTR) analysis to restore a body to its paleo-vertical and a bootstrapped oroclinal test using linear regressive techniques, including a modified foldtest around a vertical axis. Paleomagnetism.org provides an integrated approach for researchers to work with visualized (e.g. hemisphere projections, Zijderveld diagrams) paleomagnetic data. The application constructs a custom exportable file that can be shared freely and included in public databases. This exported file contains all data and can later be

    Full Text Available As hortaliças são os alimentos que mais se destacam, em artigos científicos e em jornais, quando se trata de contaminação com agrotóxicos. Isso tem levado ao aumento na demanda por produtos orgânicos por parte dos consumidores. Há, então, a necessidade de se desenvolverem tecnologias que viabilizem esses sistemas, atendendo ao consumidor e melhorando a renda dos agricultores, geralmente de base familiar. A produção de hortaliças em sistema orgânico requer tecnologias que respeitem os processos ecológicos, que promovam o aumento da matéria orgânica do solo e que sejam poupadoras de energia. Neste artigo, são discutidas algumas dessas tecnologias e resultados de pesquisas, com foco em produção de mudas, manejo e adubação do solo, adubação verde, rotação de culturas, consórcio de hortaliças, manejo de plantas espontâneas e manejo de pragas e doenças, que são práticas aprovadas pelas normas para produção orgânica e seguem os princípios agroecológicos, que contribuem para a maior eficiência energética dos sistemas produtivos e, em conjunto, para o necessário desenvolvimento do setor de produção de hortaliças orgânicas com base científica.

    Full Text Available A agricultura orgânica é ainda pouco expressiva no Brasil. Sua relevância é, no entanto, crescente, seguindo tendência observada em outros países, em especial na Europa. Este estudo analisa as características básicas do produtor de produtos orgânicos, contribuindo para preencher uma lacuna existente na literatura de economia rural. Utilizando informações primárias sobre agricultores orgânicos da região próxima à cidade de Curitiba, Paraná, identificamos as suas características pessoais e econômicas, por meio de estatística descritiva, análise de correlação e regressão linear múltipla. Os produtores foram divididos em dois grupos: o primeiro com aqueles que ainda estão em conversão para a agricultura orgânica e o segundo grupo composto por produtores orgânicos que já obtiveram a certificação de seus produtos. Os resultados obtidos indicam que alta participação de capital próprio no financiamento da produção e elevado nível de escolaridade são duas das características mais marcantes dos produtores rurais orgânicos paranaenses. Outras características que influenciam o resultado líquido da atividade são a disponibilidade de mão de obra e a integração de atividades agrícolas, pecuárias e florestais.Organic agriculture is still inexpressive in Brazil. Its relevance, however, has been growing significantly, following international trends. This study analyzes basic characteristics of organic producers, contributing to the present level of knowledge on this matter in Brazil.

    Neuronal morphology affects network connectivity, plasticity, and information processing. Uncovering the design principles and functional consequences of dendritic and axonal shape necessitates quantitative analysis and computational modeling of detailed experimental data. Digital reconstructions provide the required neuromorphological descriptions in a parsimonious, comprehensive, and reliable numerical format. NeuroMorpho.Org is the largest web-accessible repository service for digitally reconstructed neurons and one of the integrated resources in the Neuroscience Information Framework (NIF). Here we describe the NeuroMorpho.Org approach as an exemplary experience in designing, creating, populating, and curating a neuroscience digital resource. The simple three-tier architecture of NeuroMorpho.Org (web client, web server, and relational database) encompasses all necessary elements to support a large-scale, integrate-able repository. The data content, while heterogeneous in scientific scope and experimental origin, is unified in format and presentation by an in house standardization protocol. The server application (MRALD) is secure, customizable, and developer-friendly. Centralized processing and expert annotation yields a comprehensive set of metadata that enriches and complements the raw data. The thoroughly tested interface design allows for optimal and effective data search and retrieval. Availability of data in both original and standardized formats ensures compatibility with existing resources and fosters further tool development. Other key functions enable extensive exploration and discovery, including 3D and interactive visualization of branching, frequently measured morphometrics, and reciprocal links to the original PubMed publications. The integration of NeuroMorpho.Org with version-1 of the NIF (NIFv1) provides the opportunity to access morphological data in the context of other relevant resources and diverse subdomains of neuroscience, opening

    Full Text Available There are many public health benefits to cycling, such as chronic disease reduction and improved air quality. Real and perceived concerns about safety are primary barriers to new ridership. Due to limited forums for official reporting of cycling incidents, lack of comprehensive data is limiting our ability to study cycling safety and conduct surveillance. Our goal is to introduce BikeMaps.org, a new website developed by the authors for crowd-source mapping of cycling collisions and near misses. BikeMaps.org is a global mapping system that allows citizens to map locations of cycling incidents and report on the nature of the event. Attributes collected are designed for spatial modelling research on predictors of safety and risk, and to aid surveillance and planning. Released in October 2014, within two months the website had more than 14,000 visitors and mapping in 14 countries. Collisions represent 38% of reports (134/356 and near misses 62% (222/356. In our pilot city, Victoria, Canada, citizens mapped data equivalent to about one year of official cycling collision reports within two months via BikeMaps.org. Using report completeness as an indicator, early reports indicate that data are of high quality with 50% being fully attributed and another 10% having only one missing attribute. We are advancing this technology, with the development of a mobile App, improved data visualization, real-time altering of hazard reports, and automated open-source tools for data sharing. Researchers and citizens interested in utilizing the BikeMaps.org technology can get involved by encouraging citizen mapping in their region.

    Laboratory instruction of neuroscience is often limited by the lack of physical resources and supplies (e.g., brains specimens, dissection kits, physiological equipment). Online databases can serve as supplements to material labs by providing professionally collected images of brain specimens and their underlying cellular populations with resolution and quality that is extremely difficult to access for strictly pedagogical purposes. We describe a method using two online databases, the Neuromorpho.org and the Allen Brain Atlas (ABA), that freely provide access to data from working brain scientists that can be modified for laboratory instruction/exercises. Neuromorpho.org is the first neuronal morphology database that provides qualitative and quantitative data from reconstructed cells analyzed in published scientific reports. The Neuromorpho.org database contains cross species and multiple neuronal phenotype datasets which allows for comparative examinations. The ABA provides modules that allow students to study the anatomy of the rodent brain, as well as observe the different cellular phenotypes that exist using histochemical labeling. Using these tools in conjunction, advanced students can ask questions about qualitative and quantitative neuronal morphology, then examine the distribution of the same cell types across the entire brain to gain a full appreciation of the magnitude of the brain's complexity.

    2010-06-01

    ProteomeCommons.org has implemented a resource that incorporates concepts of Web 2.0 social networking for collaborative annotation of data sets placed in the Tranche repository. The annotation tools are part of a project management resource that is effective for individual laboratories or large distributed groups. The creation of the resource was motivated by the need for a way to encourage annotation of data sets with high accuracy and compliance rates. The system is designed to respond to the dynamic nature of research in an easy-to-use fashion through the use of a dynamic data model that does not inhibit the innovation that is important for basic research. Placing the annotation tool within a project manager allows annotation to occur over the life of the project and provides the security and monitoring capabilities needed for large or small collaborative projects. The resource effectively supports distributed groups of investigators working on common data sets and is available immediately at https://ProteomeCommons.org . In addition, a silver compliant data resource based on ProteomeCommons.org has been developed for cancer Biomedical Informatics Grid (caBIG) to allow much broader access to the annotations describing data sets in the Tranche repository.

    Full Text Available Ante un modelo intensivo en el uso de agroquímicos y sus consecuencias en la salud y en el medio ambiente, los alimentos orgánicos emergen como una opción de producción sustentable y saludable para los consumidores. Este artículo expone los resultados de un estudio sobre los factores generales que organizan la representación social de los alimentos frescos orgánicos en tres grupos de consumidores en San Cristóbal de Las Casas, Chiapas. El estudio se realizó con dispositivos cuantitativos y cualitativos con 250 consumidores en tres espacios de venta. Los resultados muestran similitudes y diferencias según grupo social estudiado. Los tres casos comparten preocupaciones por la salud las cuales se enmarcan en diversos factores de riesgo. Las diferencias se muestran en cuanto a sus posicionamientos políticos e ideológicos así como por su oportunidad de acceso a los alimentos orgánicos. La escolaridad no fue determinante para diferenciar las representaciones sociales emitidas.

    Slope instability and material removal from the overriding plate are common in frontal wedges of subduction-accretionary complexes, form mass-transport deposits (MTDs), and play an important role in controlling the internal dynamics of a critical taper Coulomb wedge and its slope instability. We present different examples of ancient MTDs emplaced during the late Cretaceous-Miocene evolution of the External Ligurian accretionary wedge and the related wedge-top basins (Epiligurian Units Auct.) in the NW-Apennines, Italy. These MTDs consist of sedimentary mélanges or olistostromes and display heterogeneous deformation controlled by the degree of sediment consolidation and the velocity of gravitational processes (Festa et al., 2010 IGR; Pini et al., 2011 Springer Book). Decimeter- to meter-thick shear zones associated with localized visco-plastic deformation and highly disturbed rounded and/or subangular blocks randomly distributed in a brecciated matrix form the two end-members of structures. Crosscutting relationships between MTDs and coherent successions, tectonic mélanges - broken formation and injection bodies (shaly-dykes and/or diapirs) allow us to document their time-progressive development, the correlation with tectonic and diapiric processes, and the material redistribution forming polygenic mélanges in the frontal part of the External Ligurian accretionary wedge. Out-of-sequence "megathrust" and strike-slip faulting, fluid overpressure, presence of low-permeable layers and methane-rich fluid circulation in the sedimentary column were the main factors that controlled the emplacement of various MTDs. In all the examples described, mass-transport was closely associated and had mutual interactions with tectonic and diapiric processes (Festa, 2011 GSA Sp Publ). Tectonics played the most prominent role (directly and indirectly), whereas fluid flow and overpressure strongly controlled the mechanical behavior of sediments and facilitated the emplacement of

    EarthRef.org is the common host and (co-) developer of a range of earth science databases and IT resources providing a test bed for a Cyberinfrastructure in Earth Science and Education (CIESE). EarthRef.org data base efforts include in particular the Geochemical Earth Reference Model (GERM), the Magnetics Information Consortium (MagIC), the Educational Resources for Earth Science Education (ERESE) project, the Seamount Catalog, the Mid-Ocean Ridge Catalog, the Radio-Isotope Geochronology (RiG) initiative for CHRONOS, and the Microbial Observatory for Fe oxidizing microbes on Loihi Seamount (FeMO; the most recent development). These diverse databases are developed under a single database umbrella and webserver at the San Diego Supercomputing Center. All the data bases have similar structures, with consistent metadata concepts, a common database layout, and automated upload wizards. Shared resources include supporting databases like an address book, a reference/publication catalog, and a common digital archive making database development and maintenance cost-effective, while guaranteeing interoperability. The EarthRef.org CIESE provides a common umbrella for synthesis information as well as sample-based data, and it bridges the gap between science and science education in middle and high schools, validating the potential for a system wide data infrastructure in a CIESE. EarthRef.org experiences have shown that effective communication with the respective communities is a key part of a successful CIESE facilitating both utility and community buy-in. GERM has been particularly successful at developing a metadata scheme for geochemistry and in the development of a new electronic journal (G-cubed) that has made much progress in data publication and linkages between journals and community data bases. GERM also has worked, through editors and publishers, towards interfacing databases with the publication process, to accomplish a more scholarly and database friendly data

    This contribution provides an overview of the features of Paleomagnetism.org, a new open-source online environment for paleomagnetic analysis that is supported by all modern browsers on multiple platforms. The core functionality of Paleomagnetism.org is written in JavaScript and maintains an interactive website in which paleomagnetic data can be interpreted, evaluated, visualized, and exported. Although being an online platform, the data processing is performed client-sided within the browser to respect the integrity of the data and users. In the interpretation portal, principle component analysis (Kirschvink et al., 1981) can be applied on visualized demagnetization data (Zijderveld, 1967). The interpreted directions and great circles can be combined using the iterative procedure of (McFadden and McElhinny, 1988). The resulting magnetic directions can be used in the statistics portal or exported as raw tabulated data and figures. The available tools in the statistics portal cover standard Fisher statistics for directional data and virtual geomagnetic poles (Fisher, 1953; Butler, 1992; Deenen et al., 2011). Other tools include the eigenvector approach foldtest (Tauxe and Watson, 1994), a bootstrapped reversal test (Tauxe et al., 2009), and the classical reversal test of (McFadden and McElhinny, 1990). An implementation exists for the detection and correction of inclination shallowing in sediments (Tauxe and Kent, 2004; Tauxe et al., 2008) and a module to visualize custom or default APWP reference frames (Torsvik et al., 2012; Kent and Irving, 2010; Besse and Courtillot, 2002) for continent-bearing plates. Paleomagnetism.org provides an integrated approach for researchers to export tabulated and visualized (e.g. equal area projections) paleomagnetic data. The portals construct a custom exportable file that can be shared with other researchers and included in public databases. With a publication, this custom file can be appended and would contain all data used in the

    Full Text Available El desarrollo acelerado de las neurociencias en las últimas dos décadas permitió rescatar al cerebro de las sombras cartesianas donde se encontraba condenado, demostrándose que todo fenómeno psíquico, normal o morboso, tiene como sustento material a este órgano gestor de las funciones psíquicas. De esta manera quedó esclarecido que los trastornos mentales desencadenados por acontecimientos psicosociales estresantes actúan sobre el cerebro, provocando cambios neuroquímicos a nivel molecular responsables de la sintomatología que los tipifica, conjugándose etiopatogénicamente los factores biológicos, psicológicos y sociales gestores de estos desórdenes mentales. (1 Se distinguen en psiquiatría dos tipos de perfiles clínicos que los clásicos semiólogos clasificaron en síndromes orgánicos y funcionales; los primeros causados por alteraciones estructurales a nivel histopatológico en el cerebro o sus envolturas, nombradas afecciones orgánicas propiamente dichas, y síntomáticas cuando afectan el metabolismo cerebral a distancia; los segundos sustentan los cambios a nivel molecular, afectando la constitución química del cerebro por factores psicosociales, hereditarios y congénitos. (1 Los avances neurobiológicos esclarecen la multicausalidad de los trastornos mentales y el papel organogénico del cerebro, sustentado en su capacidad intrínseca de reflejar la realidad objetiva, que al perderse origina el espectro psicopatológico que hoy conocemos.

    2015-06-01

    The manganese ore of Praborna (Italian Western Alps) is embedded within a metasedimentary sequence belonging to a subduction mélange equilibrated at high-pressure (HP) conditions (ca. 2 GPa) during the Alpine orogenesis. The pervasive veining of the ore and the growth of "pegmatoid" HP minerals suggest that these Mn-rich rocks strongly interacted with slab-derived fluids during HP metamorphism. These rocks are in textural and chemical equilibrium with the veins and in contact with sulphide- and magnetite-bearing metabasites at the bottom of the sequence. They contain braunite (Mn2+Mn3+6SiO12), quartz, pyroxmangite (Mn2+SiO3), and minor hematite, omphacite, piemontite and spessartine-rich garnet. Sulphides are absent in the Mn-rich rocks, whereas sulphates (barite, celestine) occur together with As- and Sb-oxides and silicates. This rock association provides an excellent natural laboratory to constrain the redox conditions in subducting oceanic slab mélanges at HP and fluid-present conditions. Similarly to Fe-bearing minerals, Mn oxides and silicates can be regarded as natural redox-sensors. A thermodynamic dataset for these Mn-bearing minerals is built, using literature data as well as new thermal expansion parameters for braunite aud pyrolusite, derived from experiments. Based on this dataset and the observed assemblages at Praborna, thermodynamic calculations show that these mélange rocks are characterised by ultra-oxidized conditions (∆FMQ up to + 12.7) if the chemical potential of oxygen (or the oxygen fugacity fO2) is accounted for. On the other hand, if the molar quantity of oxygen is used as the independent state variable to quantify the bulk oxidation state, the ore appears only moderately oxidized and comparable to typical subduction-slab mafic eclogites. Such an apparent contradiction may happen in rock systems whenever oxygen is improperly considered as a perfectly mobile component. In the Earth's mantle, redox reactions take place mainly between

This is the first preliminary report on the microbial diversity of casing soils and demonstrates the presence of Acinetobacter spp. that has not been previously described in casing material.

  11. Are seasonal calving dynamics forced by buttressing from ice mélange or undercutting by melting? Outcomes from full-Stokes simulations of Store Gletscher, West Greenland

    2014-07-01

    Full Text Available We use a full-Stokes 2-D model (Elmer/Ice to investigate the flow and calving dynamics of Store Gletscher, a fast flowing outlet glacier in West Greenland. Based on a new, subgrid-scale implementation of the crevasse depth calving criterion, we perform two sets of simulations; one to identify the primary forcing mechanisms and another to constrain future stability. We find that the mixture of icebergs and sea-ice, known as ice mélange or sikussak, is principally responsible for the observed seasonal advance of the ice front, whereas submarine melting plays a secondary role. Sensitivity analysis demonstrates that the glacier's calving dynamics are sensitive to seasonal perturbation, but are stable on interannual timescales due to the glacier's topographic setting. Our results shed light on the dynamics of calving glaciers while explaining why neighbouring glaciers do not necessarily respond synchronously to changes in atmospheric and oceanic forcing.

A proposta da primeira etapa da pesquisa da qual este artigo é resultado se concentrou no estudo das cartas inéditas trocadas entre Curt Lange e o mais renomado modernista brasileiro, Mário de Andrade. O ineditismo destas cartas, ainda não utilizadas como objeto de pesquisa até aquele momento, demonstrou a relevância desta investigação que ainda está em andamento. Apesar do foco da primeira etapa se concentrar nas cartas trocadas entre Lange e Mário de Andrade, durante a pesquisa, diversos outros atores tais como, Villa-Lobos, Camargo Guarnieri, Guerra-Peixe, Koellreuter e Claudio Santoro apareceram dentro de uma rede de sociabilidades tecida pelo projeto musicológico de Curt Lange: o Americanismo Musical. A ampliação do estudo desta rede se concentra agora nas cartas trocadas entre Curt Lange e Cláudio Santoro (1919-1989. O presente artigo trata daquelas cartas trocadas entre os anos nos de 1942 e 1946 e os diálogos estas com esta rede mais ampla.

    High pressure igneous rocks (tonalites), generated by partial melting of subducted basaltic rocks accreted to the mantle wedge, are present in the La Corea serpentinite-matrix mélange (eastern Cuba) as centimeter- to meter-sized blocks and as concordant to crosscutting veins within high-pressure parent amphibolite blocks. The slab melts have adakitic signatures, in agreement with formation after partial melting of metabasite. Thermobarometric calculations indicate 620-680 °C and 13-15 kbar during crystallization of tonalites and down to 250-300 °C, 6 kbar during retrogression, indicating counter-clockwise P-T paths (hot subduction-cool exhumation). Free water required for melting of amphibolite at moderate temperature (700-750 °C) and moderate pressure (13-16 kbar) close to the wet basaltic solidus is inferred to have been provided after dehydration of sediments, altered basaltic crust and serpentinite of the subducting Proto-Caribbean lithosphere. Single zircon (SHRIMP) and phengite 40Ar/39Ar age data constrain the P-T-t evolution of the mélange from the timing of crystallization of melts at ~ 110-105 Ma to cooling at ~ 87-84 Ma, ca. 350 °C, ca. 9 kbar. These figures are consistent with subduction of an oblique ridge, shortly before 115 Ma. Furthermore, our data indicate very slow exhumation (ca. 1 mm/yr) in the subduction channel during the oceanic convergence stage (120-70 Ma) until final fast exhumation to the surface occurred at 70-65 Ma during a regional arc-platform collision event.

  15. Destruksie ten minste tien maal beklemtoon – ’n interpretasie van 'Kraak die aardbol langs ’n naat' van Wilma Stockenström

    Full Text Available Destruction at least ten times emphasized – an interpretation of 'Kraak die aardbol langs ’n naat' ('Cracking the earth along the seam' by Wilma Stockenström In this article the value of syntactical analysis in the interpretation of a poem is investigated from the premise that emphasis can be effected inter alia in the following ways: (a by contravening certain rules that apply in standard language usage in order to compose grammatical sentences, b the exploitation of parallel syntactical structures, and c the relationship between sentence unit and line, and line and/or stanza. These theoretical points of departure form the basis of the syntactical analysis of “Kraak die aardbol langs ’n naat” (Wilma Stockenström, in which there are numerous deviations from the expected, normal and usual ways of constructing sentences. It is by these means that the semantic values gain prominence: the attention is drawn to the deviating behaviour of mankind continuing to destruct the earth until nothing remains. It is evident that the repeated use of irony and the satirical tone of this poem also contribute to persuade the reader to behave in a way opposite to that depicted in the poem. In this way the value of a syntactical analysis of this poem is illustrated. By uncovering the micro-structures (syntactical units within the (macro- structure (the poem, underlying patterns and the place of humanity in the universe can be better understood. In this way the analysis of this poem is then linked to the field of ecocriticism.

  1. Extending ArXiv.org to Achieve Open Peer Review and Publishing

    CERN Document Server

    Boldt, Axel

    2010-01-01

    Today's peer review process for scientific articles is unnecessarily opaque and offers few incentives to referees. Likewise, the publishing process is unnecessarily inefficient and its results are only rarely made freely available to the public. Here we outline a comparatively simple extension of arXiv.org, an online preprint archive widely used in the mathematical and physical sciences, that addresses both of these problems. Under the proposal, editors invite referees to write public and signed reviews to be attached to the posted preprints, and then elevate selected articles to "published" status.

    Full Text Available This research aims to approach the role of Change.org as an electronic petition platform in Spain, where there are no alternatives managed by public authorities. By a qualitative content analysis and a semi-structured interview, we research the business model of the page, in order to examine its data protection policy, its user verification system and, in a broader perspective, the legal framework in which it works. Results show the project is not related to Spanish law, it has a weak authentication system and its benefits are based on cost per acquisition.

    Bach, Paula M.; Carroll, John M.

    We describe two cases of open user experience (UX) design using the Firefox web browser and OpenOffice.org office suite as case studies. We analyze the social complexity of integrating UX practices into the two open source projects using activity awareness, a framework for understanding team performance in collective endeavors of significant scope, duration, and complexity. The facets of activity awareness are common ground, community of practice, social capital, and human development. We found that differences between the communities include different strategies for community building, UX status in the community, type of open UX design, and different ways to share information.

    Hippocampome.org is a comprehensive knowledge base of neuron types in the rodent hippocampal formation (dentate gyrus, CA3, CA2, CA1, subiculum, and entorhinal cortex). Although the hippocampal literature is remarkably information-rich, neuron properties are often reported with incompletely defined and notoriously inconsistent terminology, creating a formidable challenge for data integration. Our extensive literature mining and data reconciliation identified 122 neuron types based on neurotransmitter, axonal and dendritic patterns, synaptic specificity, electrophysiology, and molecular biomarkers. All ∼3700 annotated properties are individually supported by specific evidence (∼14,000 pieces) in peer-reviewed publications. Systematic analysis of this unprecedented amount of machine-readable information reveals novel correlations among neuron types and properties, the potential connectivity of the full hippocampal circuitry, and outstanding knowledge gaps. User-friendly browsing and online querying of Hippocampome.org may aid design and interpretation of both experiments and simulations. This powerful, simple, and extensible neuron classification endeavor is unique in its detail, utility, and completeness.

    2015-05-01

    Online crowdfunding platforms like DonorsChoose.org and Kick-starter allow specific projects to get funded by targeted contributions from a large number of people. Critical for the success of crowdfunding communities is recruitment and continued engagement of donors. With donor attrition rates above 70%, a significant challenge for online crowdfunding platforms as well as traditional offline non-profit organizations is the problem of donor retention. We present a large-scale study of millions of donors and donations on DonorsChoose.org, a crowdfunding platform for education projects. Studying an online crowdfunding platform allows for an unprecedented detailed view of how people direct their donations. We explore various factors impacting donor retention which allows us to identify different groups of donors and quantify their propensity to return for subsequent donations. We find that donors are more likely to return if they had a positive interaction with the receiver of the donation. We also show that this includes appropriate and timely recognition of their support as well as detailed communication of their impact. Finally, we discuss how our findings could inform steps to improve donor retention in crowdfunding communities and non-profit organizations.

    Glucocorticoid receptors play an important role in the regulation of the activity of the hypothalamo-pituitary-adrenal axis, and are thought to be involved in the pathophysiology of depressive disorders. The present study investigated the effect of the specific glucocorticoid receptor antagonist ORG 34116 (a substituted 11,21 bisarylsteroid compound) in the tree shrew (Tupaia belangeri) chronic psychosocial stress model, an established animal model for depressive disorders. Animals were stressed for 10 days before treatment with ORG 34116 started (25 mg/kg p.o. for 28 days). Stress induced a decrease in body weight, which just failed significance, whereas ORG 34116 did not affect body weight in stress and control animals. ORG 34116 enhanced the stress-induced increase in the concentration of urinary-free cortisol, although no differences between the different experimental groups existed during the last week of treatment. In stressed animals, ORG 34116 did not affect marking behavior, but decreased locomotor activity. Post mortem analysis of 5-HT(1A) receptors revealed a decreased affinity of 3[H]-8-OH-DPAT (3[H]-8-hydroxy-2-[di-n-propylamino]tetralin) binding sites in the hippocampus of animals treated with the glucocorticoid receptor antagonist. In conclusion, under our experimental conditions, the glucocorticoid receptor antagonist ORG 34116 did not normalize the depressive-like symptoms in the psychosocial stress model of male tree shrews. This finding, however, does not exclude that specific central, neuroendocrine and behavioral features are affected by the compound.

    VHub (short for VolcanoHub, and accessible at vhub.org) is an online platform for barrier free access to high end modeling and simulation and collaboration in research and training related to volcanoes, the hazards they pose, and risk mitigation. The underlying concept is to provide a platform, building upon the successful HUBzero software infrastructure (hubzero.org), that enables workers to collaborate online and to easily share information, modeling and analysis tools, and educational materials with colleagues around the globe. Collaboration occurs around several different points: (1) modeling and simulation; (2) data sharing; (3) education and training; (4) volcano observatories; and (5) project-specific groups. VHub promotes modeling and simulation in two ways: (1) some models can be implemented on VHub for online execution. VHub can provide a central warehouse for such models that should result in broader dissemination. VHub also provides a platform that supports the more complex CFD models by enabling the sharing of code development and problem-solving knowledge, benchmarking datasets, and the development of validation exercises. VHub also provides a platform for sharing of data and datasets. The VHub development team is implementing the iRODS data sharing middleware (see irods.org). iRODS allows a researcher to access data that are located at participating data sources around the world (a cloud of data) as if the data were housed in a single virtual database. Projects associated with VHub are also going to introduce the use of data driven workflow tools to support the use of multistage analysis processes where computing and data are integrated for model validation, hazard analysis etc. Audio-video recordings of seminars, PowerPoint slide sets, and educational simulations are all items that can be placed onto VHub for use by the community or by selected collaborators. An important point is that the manager of a given educational resource (or any other

    White Dwarf Research Corporation is a 501(c)(3) non-profit organization dedicated to scientific research and public education on topics relevant to white dwarf stars. It was founded in 1999 in Austin, Texas to help fulfill the need for an alternative research center where scarce funding dollars could be used more efficiently, and to provide a direct link between astronomers who study white dwarf stars and the general public. Due to its administrative simplicity, WDRC can facilitate the funding of multi-institutional and international collaborations, provide seamless grant portability, minimize overhead rates, and actively seek non-governmental funding sources. I describe the motivation for, and current status of, one of the long-term goals of WDRC: to establish a permanent endowment for the operation of the Whole Earth Telescope.

    In some subjects with severe neurological diseases, a reduced immune response to seasonal influenza vaccine has been demonstrated. Patients with Williams or Cornelia de Lange syndrome frequently have abnormalities in neurodevelopment. This study has evaluated the immunogenicity, safety and tolerability of a monovalent 2009 pandemic influenza A/H1N1 MF59-adjuvanted vaccine in these subjects. Eighteen patients with Williams syndrome (ten males; mean age ± standard deviation [SD] 12.74 ± 4.49 years), 11 with Cornelia de Lange syndrome (six males; mean age 12.90 ± 4.85 years) and 30 age- and gender-matched healthy controls (16 males; mean age 12.49 ± 4.55 years), never vaccinated against influenza, received a dose of the vaccine between 1 and 30 November 2009. Four weeks later, the seroconversion rates in the three groups were between 72% and 80% and the seroprotection rates were 100%, with a similar increase in antibody levels. Two months later, most of the subjects remained seroconverted with no statistically significant difference between the groups, and about 94% of the patients with Williams syndrome, all of those with Cornelia de Lange syndrome and all of the healthy controls were still seroprotected. Safety and tolerability were very good, with no difference between the groups. None of the patients developed documented influenza during the study period. These results show that the immunogenicity, safety, and tolerability of a single dose of the monovalent 2009 pandemic influenza A/H1N1 MF59-adjuvanted vaccine in children and adolescents with Williams or Cornelia de Lange syndrome and moderate to severe mental disabilities is very good, and similar to that of healthy subjects.

    The Mersin Ophiolitic Complex located in southern Turkey comprises two main structural units; the Mersin Mélange, and a well-developed ophiolite succession with its metamorphic sole. The Mersin Mélange is a sedimentary complex including blocks and tectonic slices of oceanic litosphere and continental crust in different sizes. Based on different fossil groups (Radiolaria, Conodonta, Foraminifera and Ammonoidea), the age of these blocks ranges from Early Carboniferous to early Late Cretaceous. Detailed fieldwork in the central part of the Mersin Mélange resulted in identification of a number of peculiar blocks of thick basaltic pillow-and massive lava sequences alternating with pelagic-clastic sediments and radiolarian cherts. The oldest ages obtained from the radiolarian assemblages from the pelagic sediments transitional to the volcano-sedimentary succession in some blocks are middle to late Late Anisian. These pelagic sediments are overlain by thick sandstones of latest Anisian to middle Early Ladinian age. In some blocks, sandstones are overlain by clastic and pelagic sediments with lower Upper to middle Upper Ladinian radiolarian fauna. Considering the litho- and biostratigraphical data from Middle Triassic successions in several blocks in the Mersin Mélange, it is concluded that they correspond mainly to the blocks/slices of the Beysehir-Hoyran Nappes, which were originated from the southern margin of the Neotethyan Izmir-Ankara Ocean. As the pre-Upper Anisian basic volcanics are geochemically evaluated as back-arc basalts, this new age finding suggest that a segment of the Izmir-Ankara branch of the Neotethys was already open prior to Middle Triassic and was the site of intraoceanic subduction.

    We use a full-Stokes 2-D model (Elmer/Ice) to investigate the flow and calving dynamics of Store Glacier, a fast-flowing outlet glacier in West Greenland. Based on a new, subgrid-scale implementation of the crevasse depth calving criterion, we perform two sets of simulations: one to identify the primary forcing mechanisms and another to constrain future stability. We find that the mixture of icebergs and sea ice, known as ice mélange or sikussak, is principally responsible for the observed seasonal advance of the ice front. On the other hand, the effect of submarine melting on the calving rate of Store Glacier appears to be limited. Sensitivity analysis demonstrates that the glacier's calving dynamics are sensitive to seasonal perturbation, but are stable on interannual timescales due to the strong topographic control on the flow regime. Our results shed light on the dynamics of calving glaciers and may help explain why neighbouring glaciers do not necessarily respond synchronously to changes in atmospheric and oceanic forcing.

    Whole-rock compositions of muscovite-bearing amphibolite, trondhjemite, pegmatite and quartz-muscovite rocks from Sierra del Convento and La Corea mélanges (eastern Cuba), as well as mineralogy, record complex circulation of Ba-rich fluids and melts in the subduction environment. Partial melting of fluid-fluxed, MORB-derived amphibolite produced trondhjemite magmas that crystallized at depth, in some cases evolving into pegmatites. Qtz-Ms rocks probably crystallized from primary fluids derived from subducted sediments. All these rocks have elevated concentrations of large-ion lithophile elements, especially Ba (up to 11,810 ppm), presumably released from slab sediments by fluids and/or melts. Fluid-rock interaction produced crystallization of phengite in parental amphibolites. The phengite crystallized in all types of rocks is rich in Ba, with concentric zoning, characterized by Ba-rich cores and Ba-poor rims, indicating a compatible behaviour of Ba in the studied systems. Zoning in phengite is governed primarily by the celadonite (tschermak) exchange vector ((Mg,Fe)Si-(Al)-2), with more moderate contributions of the celsian (BaAl-(KSi)-1) and paragonite (NaK-1) exchange vectors. Late remobilization of Ba at relatively low temperature formed retrograde celsian. The compatible behaviour of Ba in the studied rocks strengthens the importance of the stability of phengite for the transfer of LIL elements from the subduction to the volcanic arc environments.

    The Mersin Mélange is a tectonostratigraphic unit within the allochthonous Mersin Ophiolitic Complex in the Taurides, southern Turkey. This chaotic structure consists of blocks and tectonic slices of diverse origins and ages set in a clastic matrix of Upper Cretaceous age. In this study, we examine two blocks at two different sections characterized by basaltic lava flows alternating with radiolarian-bearing pelagic sediments. The radiolarian assemblage extracted from the mudstone-chert alternation overlying the lavas yields an upper Anisian age (Middle Triassic). The immobile element geochemistry suggests that the lava flows are predominantly characterized by sub-alkaline basalts. All lavas display pronounced negative Nb anomalies largely coupled with normal mid-ocean basalt (N-MORB)-like high field strength element (HFSE) patterns. On the basis of geochemical modelling, the basalts appear to have dominantly derived from spinel-peridotite and pre-depleted spinel-peridotite sources, while some enriched compositions can be explained by contribution of garnet-facies melts from enriched domains. The overall geochemical characteristics suggest generation of these Middle Triassic lavas at an intra-oceanic back-arc basin within the northern branch of Neotethys. This finding is of significant importance, since these rocks may represent the presence of the oldest subduction zone found thus far from the Neotethyan branches. This, in turn, suggests that the rupturing of the Gondwanan lithosphere responsible for the opening of the northern branch of Neotethys should have occurred during the Lower Triassic or earlier.

    Full Text Available Ponderações sobre as emoções humanas apresentaram-se em toda a obra do bielorrusso L. S. Vigotski, desde sua juvenil crítica de arte. Nesse tópico, debateu a contribuição de vários autores: Freud, Claparède, Ribot, Lewin, Wundt. Entretanto, a perspectiva mais analisada por ele foi a teoria James-Lange. O objetivo deste artigo é discutir a extensa crítica que Vigotski dirigiu a ela no manuscrito “Utchenie ob Emotsiakh”, a qual se enquadrava numa ampla atitude teórico-metodológica do autor: a de compilar e relacionar o material fatual sem coordenação, expondo a luta de ideias filosóficas por detrás das psicológicas, de modo a abrir caminho para futuras investigações destinadas à superação do dualismo na psicologia. A partir dos principais fundamentos vigotskianos para futuros estudos, discutimos essa querela acerca das emoções, tema que o bielorrusso considerava a parte mais difícil e, possivelmente, a mais importante para o futuro da ciência psicológica.

    Mutations in the potassium channel subunit KCNQ1 cause the human severe congenital deafness Jervell and Lange-Nielsen (JLN) syndrome. We applied a gene therapy approach in a mouse model of JLN syndrome (Kcnq1(-/-) mice) to prevent the development of deafness in the adult stage. A modified adeno-associated virus construct carrying a Kcnq1 expression cassette was injected postnatally (P0-P2) into the endolymph, which resulted in Kcnq1 expression in most cochlear marginal cells where native Kcnq1 is exclusively expressed. We also found that extensive ectopic virally mediated Kcnq1 transgene expression did not affect normal cochlear functions. Examination of cochlear morphology showed that the collapse of the Reissner's membrane and degeneration of hair cells (HCs) and cells in the spiral ganglia were corrected in Kcnq1(-/-) mice. Electrophysiological tests showed normal endocochlear potential in treated ears. In addition, auditory brainstem responses showed significant hearing preservation in the injected ears, ranging from 20 dB improvement to complete correction of the deafness phenotype. Our results demonstrate the first successful gene therapy treatment for gene defects specifically affecting the function of the stria vascularis, which is a major site affected by genetic mutations in inherited hearing loss.

    Full Text Available The present study aims to determine the levels of trihalomethanes (THMs in drinking water from different Spanish cities, and assess whether the temperature and rainfall influence them. Also assess the possible association of THM to mortality from stomach cancer and bladder. For this we took water samples from 49 cities in 2002, 2005 and 2006, which were analyzed by gas chromatography coupled with mass spectrometry obtaining THM levels. Climatic classifications were made according Koppën Lang and index the data of temperature and precipitation, and finally death rates from cancer of the stomach and bladder were standardized by sex and age. We found a decrease in the levels of THMs in Spain over time, managing to be below the limits established by Royal Decree 140/2003, but three cities studied. The results indicate that climatic classifications most of the Spanish territory has a temperate climate type - Wet. However it was found that different climatic zones exhibit an influence on the levels of THMs. Nor was significant correlation of the levels of THM with cancer of stomach and bladder, but is significant between stomach cancer and Köppen climate classification. It should continue with studies that include other variables allow clarifying and / or strengthening these results.

    The Ormen Lange Onshore Processing Plant in Aukra municipality (Moere og Romsdal county) receives unprocessed gas and condensate from the Ormen Lange field in the Norwegian Sea. During processing of sales gas and condensate, the plant emits CO, Co2, Nox, CH4, NMVOC (including BTEX), SO2 and small amounts of heavy metals, as specified in the discharge permit issued by the Climate and Pollution Directorate. The plant started production in 2007, with A/S Norske Shell as operator. In general, emissions of nitrogen and sulphur-containing gasses may affect terrestrial ecosystems through acidification and fertilization of soil and vegetation. The emissions from the onshore plant are calculated to be below the current critical loads for the terrestrial nature types. However, the nitrogen background level in the area of influence is close to the critical loads for oligotrophic habitats. To be able to document any effects of emissions to air on terrestrial ecosystems, a monitoring program for vegetation and soil was established in 2008 in the area of influence from the Ormen Lange Onshore Plant. The monitoring is planned at regular intervals according to the same methods employed in 2008, with the first reanalysis in 2010. The benefits of the monitoring parameters will be continuously evaluated. Statnett has established a Reserve Power Plant with discharge permits of similar substances in the same area as the Ormen Lange Onshore Processing plant, and participates in an extended monitor program from 2010. In 2008 two monitoring sites were established, one with rather high deposition of nitrogen north of the plant within Gule-Stavmyran nature reserve in Fraena municipality (site Gulmyran) and one south of the plant on the island Gossa (site Aukra). Deposition values have been estimated by the Norwegian Institute for Air Research (NILU). Within each site integrated monitoring of the species composition of the vegetation, plant growth, and chemical content of plants and soil is

    We used the K-Ar ages of clay-sized mineral grains to investigate the timing of activity on the Minami-Awa Fault, which is a fossil seismogenic fault along a subducting plate interface separating the coherent strata of the Shimanto accretionary complex to the north from the tectonic mélange to the south. The K-Ar ages from the matrix shale of the mélange range from 85 to 48 Ma and decrease with decreasing amount of detrital mica, indicating that they record a mixture of authigenic illite related to burial diagenesis and detrital mica. In contrast, the K-Ar ages of an ultracataclasite within the fault core are significantly younger, ranging from 29 to 23 Ma, and are unrelated to grain size and amount of detrital mica. This indicates that s Ar diffused completely from the ultracataclasite between 29 and 23 Ma, which postdates the formation of authigenic illite by at least several million years. The diffusion of 40Ar in the ultracataclasite was probably caused by frictional heating or high-temperature fluid migration that occurred when the fault was reactivated. The results indicate that seismogenic faults that separate tectonic mélange from coherent strata in accretionary complexes may slip, not only during accretion, but also long after accretion.

    Las nubes moleculares son regiones de formación de estrellas, con temperaturas cinéticas entre 10-50 K y densidades de 103-106 átomos cm-3. Su materia está formada por gas y polvo interestelar. Estas partículas de polvo están cubiertas por una fina capa de hielo, de unos 0.01 μm, que contiene H2O y a menudo CO, CO2, CH3OH y NH3. El hielo es presumiblemente irradiado por fotones ultravioleta y rayos cósmicos en las zonas poco profundas de las nubes moleculares y las regiones circunestelares. En un sistema de vacío, P ˜ 10-7 mbar, simulamos la deposición de hielo a partir de 10 K y la irradiación ultravioleta por medio de una lámpara de descarga de hidrógeno activada con microondas. La evolución del hielo se observa por medio de un espectrómetro infrarrojo. De este modo es posible determinar la composición del hielo observado en el medio interestelar y predecir la presencia de moléculas aún no detectadas en el espacio, que han sido producto del procesamiento del hielo en nuestros experimentos. También es posible calentar el sistema hasta temperatura ambiente para sublimar el hielo depositado. Cuando el hielo ha sido previamente irradiado, se observa un residuo compuesto por moléculas orgánicas complejas, algunas prebióticas, como varios ácidos carboxílicos, aminas, amidas, ésteres y en menor proporción moléculas heterocíclicas y aminoácidos. Algunas de estas moléculas podrían detectarse en estado gaseoso por medio de observaciones milimétricas y de radio. También podrían estar presentes en el polvo cometario, cuyo análisis químico está planeado por las misiones Stardust y Rosetta. Mientras tanto, nuestro grupo está llevando a cabo el análisis de partículas de polvo interplanetario (IDPs), algunas de las cuales pueden ser de origen cometario. Al igual que ocurre con los productos obtenidos por irradiación del hielo en nuestros experimentos, algunas IDPs son ricas en material orgánico que contiene oxígeno.

    2006-12-01

    The media and public policy debate suffer from an extreme form of Attention Deficit Disorder. Compared to the daily news cycle, the progress of scientific debate within the peer-reviewed literature is extremely slow. This puts serious scientists who work in relatively politicised fields (global warming, evolution, stem cell research and the like) at a huge disadvantage when it comes to having their voices heard above the noise. Since Dec 2004, RealClimate.org has been operating as a group blog (a web-based journal) run by climate scientists for interested members of the public and the media. The aim has been to provide the context for climate-related news stories that is often missing in the mainstream media and to explain the basics of our field to the often confused, but curious, members of the public. In particular, it has provided rapid reaction to mis-uses and abuses of scientific results by policy advocates across the spectrum. Reactions to the blog have been overwhelmingly (but not uniformly) positive from both professionals in the media, the scientific community and the public. It has been described as the 'go-to site' for climate science in the New York Times, and received a Scientific American Science and Technology Web award in 2005. I will discuss what impacts RealClimate may have had and the pluses and minuses of trying to reach the public through this kind of outlet.

    Information about disease management in winter wheat (Triticum aestiva) in eight European countries was collated and analysed by scientists and extension workers within the European Network for the Durable Exploitation of Crop Protection Strategies (ENDURE). This included information about speciifc disease thresholds, decision support systems, host varieties, disease prevalence and pathogen virulence. Major differences in disease prevalence and economic importance were observed. Septoria tritici blotch (Mycosphaerella graminicola) was recognized as the most yield reducing disease in countries with intensive wheat production, but also rust diseases (Puccinia striiformis andPuccinia triticina), powdery mildew (Blumeria graminis) and Fusarium head blight (Fusarium spp.) were seen as serious disease problems. Examples of current integrated pest management (IPM) strategies in different countries have been reported. Disease management and fungicide use patterns showed major differences, with an average input equivalent to 2.3 full dose rates (TFI) in the UK and a TFI of 0.6 in Denmark. These differences are most likely due to a combination of different cropping systems, climatic differences, disease prevalence, and socio-economic factors. The web based information platform www.eurowheat.org was used for dissemination of information and results includinginformation on control thresholds, cultural practices which can inlfuence disease attack, fungicide efifcacy, fungicide resistance, and pathogen virulence, which are all elements supporting IPM for disease control in wheat. The platform is open to all users. The target groups of EuroWheat information are researchers, advisors, breeders, and similar partners dealing with disease management in wheat.

    Relatively few patients with Cornelia de Lange syndrome (CdLS) due to SMC1A mutation have been reported, limiting understanding of the full extent of the phenotype. Compared to children with classic NIPBL-associated CdLS, patients with SMC1A-associated CdLS have a milder physical phenotype with prominent intellectual disability, high rate of cleft palate and absence of limb reductions. We present a patient with SMC1A-associated CdLS who had typical features including developmental delay, seizure disorder, feeding difficulties, hirsutism, and cleft palate. She also was found to have three novel features: (i) left ventricular non-compaction (LVNC) cardiomyopathy; (ii) microform cleft lip; and (iii) severe hyperopia and astigmatism. These features have implications regarding potential insight into the pathogenesis of the disorder, screening, and medical management. Hypertrophic cardiomyopathy has previously been reported in SMC1A-associated CdLS, but to our knowledge this is the first reported child with LVNC. Previous reports have included children with isolated clefts of the palate without involvement of the lip. When cleft palate alone is associated with a disorder, the underlying pathophysiology for clefting is sometimes secondary due to mechanical blocking of the fusion of the palatal shelves with the developing tongue. The presence of microform cleft lip in this patient suggests that the pathophysiology of clefting in SMC1A is primary rather than secondary. Few studies report ophthalmologic findings specific to SMC1A. Based on these findings, LVNC cardiomyopathy and cleft lip should be considered features of SMC1A-associated CdLS. All patients should receive echocardiogram and undergo thorough ophthalmologic evaluation as part of routine CdLS care. © 2016 Wiley Periodicals, Inc.

    In this study, the frequency of mass-wasting events and past storminess has been reconstructed throughout the Holocene (11,500 cal yr BP to present) from lacustrine sediments in lake Trehynnvatnet (33 m a.s.l.), which is located in a glacially carved valley at Nykvåg on the outmost coast of western Langøya, Vesterålen, northern Norway. Sediment cores (∼2-5 m long) have been examined by use of high-resolution magnetic susceptibility and XRF-scanning as well as grain size and loss-on-ignition analysis. In total 35 episodic event layers have been identified throughout the Holocene. The majority of these events are characterized as discrete coarse-grained sediment layers followed by normal grading, and are related to past mass-wasting activity within the catchment. Periods with high mass-wasting activity are dated to 11,000-10,500, 5500-4500, 4000-3500, 3000-2500, 2000-1000 and 500-0 cal yr BP. The continuous input of sand grains (>250 μm) has been systematically investigated throughout the sediment cores. The sand grains are related to catchment samples from the sandy beach deposits in Sandvikbukta c. 750 m away in SW direction, and are suggested to indicate (niveo-) aeolian influx to the lake. The content of sand grains varies greatly throughout the record, although there is a clear increase in influx of sand during the last 2800 years. Periods with high aeolian influx are proposed to indicate increased storminess, which occurred between 1600 and 1550 (350-400 CE), 1400-1300 (450-550 CE), 750-550 (1200-1400 CE) and 250-20 cal yr BP (1700-1930 CE), which to some degree coincides with periods of increased storminess and winter precipitation recorded in other studies around the North Eastern Atlantic region.

    Full Text Available Abstract Background Long QT syndrome (LQTS is a cardiac disorder characterized by prolonged QT intervals on electrocardiograms (ECG, ventricular arrhythmias, and sudden death. Clinically, two inherited forms of LQTS have been defined: autosomal dominant LQTS or Romano-Ward syndrome (RWS not associated with deafness and autosomal recessive LQTS or Jervell and Lange-Nielsen syndrome (JLNS associated with deafness. Methods A Chinese family with both RWS and JLNS was identified. Family members were diagnosed based on the presence of a prolonged QT interval as seen on a 12-lead ECG and a medical history of syncope, palpitation, and deafness. Mutational studies in the KCNQ1 potassium channel gene were performed using direct DNA sequence analysis and restriction length polymorphism analysis. Results The proband in the Chinese family and her brother had previously been diagnosed with JLNS, and two other members were affected with RWS. The proband was also affected with atrial fibrillation. A single nucleotide substitution of C to T at nucleotide 965 of KCNQ1 was identified, and the mutation resulted in the substitution of a threonine residue at codon 322 by a methionine residue (T322M. The novel heterozygous T322M mutation was identified in two patients with RWS, one member with borderline QTc, and two normal family members. The two JLNS patients in the family carried the homozygous T322M mutation. The T322M mutation was not found in 200 Chinese normal controls. Conclusion Our results suggest that T322M is a novel mutation that caused RWS with high intrafamilial variability in the heterozygous carriers and typical JLNS in the homozygous carriers within this Chinese family. The T322M mutation is the first mutation identified for JLNS in the Chinese population.

  7. A Method to Estimate Friction Coefficient from Orientation Distribution of Meso-scale Faults: Applications to Faults in Forearc Sediment and Underplated Tectonic Mélange

    Friction coefficients along faults control the brittle strength of the earth's upper crust, although it is difficult to estimate them especially of ancient geological faults. Several previous studies tried to determine the friction coefficient of meso-scale faults from their orientation distribution as follows. Fault-slip analysis through stress tensor inversion techniques gives principal stress axes and a stress ratio, which allows us to draw a normalized Mohr's circle. Assuming that a faulting occurs when the ratio of shear stress to normal stress on it, i.e., the slip tendency, exceeds the friction coefficient, one can find a linear boundary of distribution of points corresponding to faults on Mohr diagram. The slope of the boundary (friction envelope) provides the friction coefficient. This method has a difficulty in graphically and manually recognizing the linear boundary of distribution on the Mohr diagram. This study automated the determination of friction coefficient by considering the fluctuations of fluid pressure and differential stress. These unknown factors are expected to make difference in density of points representing faults on the Mohr diagram. Since the density is controlled by the friction coefficient, we can optimize the friction coefficient so as to explain the density distribution. The method was applied to two examples of natural meso-scale faults. The first example is from the Pleistocene Kazusa Group, central Japan, which filled a forearc basin of the Sagami Trough. Stress inversion analysis showed WNW-ENE trending tensional stress with a low stress ratio. The friction coefficient was determined to be around 0.66, which is typical value for sandstone. The Second example is from an underplated tectonic mélange in the Cretaceous to Paleogene Shimanto accretionary complex in southwest Japan along the Nankai Trough. The stress condition was determined to be an axial compression perpendicular to the foliation of shale matrix. The friction

    Full Text Available Agricultural production systems have to combine management practices in order to sustain soil's profitability and quality. Organic farming is gaining worldwide acceptance and has been expanding at an annual rate of 20% in the last decade, accounting for over 24 million hectares worldwide. Organic practices avoid applications of synthetic fertilizers and pesticides, rely on organic inputs and recycling for nutrient supply, and emphasize cropping system design and biological processes for pest management, as defined by organic farming regulation in the world. In comparison with conventional farming, organic farming has potential benefits in improving food quality and safety. Plant production in organic farming mainly depends on nutrient release as a function of mineralization processes in soils. The build-up of a large and active soil microbial biomass is important pool of accessible nutrients, therefore, is an important priority in organic farming. In organic farming, there is positive effect of quantity and quality of inputs of organic residues on soil microbial biomass. In this way, the organic systems are extremely important for the increase of the soil fertility and the maintenance of the environmental sustainability.A produção agrícola tem de combinar práticas para prover a sustentabilidade do solo. A agricultura orgânica está ganhando aceitação mundial e cresce à taxa anual de 20% na última década, contabilizando mais de 24 milhões de hectares. As práticas orgânicas evitam o uso de fertilizantes sintéticos e pesticidas, enfatiza a aplicação de matéria orgânica, como também a reciclagem de nutrientes e de processos biológicos para manejo de pragas, através das regras dos sistemas orgânicos no mundo. Em comparação com a agricultura convencional, os sistemas orgânicos têm potencial de melhorar a qualidade e a segurança dos alimentos. A produção das plantas no sistema orgânico depende da liberação de nutrientes

    The aim of the study on the title subject is to inventory the bottlenecks and problems for stakeholders to ask the right questions with respect to energy transition and the long-term energy research strategy programmes in the Netherlands. Recommendations to solve the problems are presented. The most important effects of analyzing the so-called articulation of questions must be (1) an improved connection between the long-term research programme and the needs of industry and businesses, and (2) increasing the possibilities to apply for subsidies. [Dutch] Energieonderzoek en -innovatie vormen belangrijke en aan elkaar gerelateerde onderdelen van het energiebeleid om de overgang naar een duurzame energiehuishouding te realiseren. Voor de lange termijn bestaan op deze gebieden twee richtinggevende beleidssporen: de energieonderzoek subsidie: lange termijn (EOS-LT) en de energietransitie. In het eerste beleidsspoor, EOS-LT, wordt het publiek gefinancierd lange termijn energieonderzoek op een beperkt aantal aandachtsgebieden gericht. Hiervoor zijn lange termijn onderzoeksprogramma's opgesteld, waarin onderzoeksthema's zijn opgenomen die in aanmerking komen voor subsidie. Het tweede beleidsspoor, de energietransitie, richt zich op niet alleen op de technologische, maar ook de institutionele en politiek-bestuurlijke vernieuwingen om de duurzame energiehuishouding te realiseren. In samenspraak met verschillende stakeholders worden langetermijnvisies geformuleerd en de mogelijke wegen om deze visies te realiseren. Op basis hiervan worden kortetermijnexperimenten opgesteld om deze wegen te verkennen en aan te scherpen. EOS-LT en energietransitie zijn grotendeels onafhankelijk van elkaar tot stand gekomen, maar er zijn pogingen ondernomen om de aansluiting tussen beide trajecten te versterken. Het probleem in de praktijk is echter dat de vraag naar industrieel en fundamenteel energieonderzoek vanuit energietransitie tot nu in onvoldoende mate wordt gearticuleerd

    For the assay of the antidepressant compound mianserin hydrochloride (Org GB 94) in human plasma, a mass fragmentographic method, using the deuterated analogue as internal standard and a high-performance liquid chromatographie sample clean-up procedure has been developed. The assay specifications obtained are a lower limit for reliable measurements of 1 ng/ml, and accuracy of ca. 0.01 ng/ml, a precision of 6--7% and a capacity of about 60 samples per day. The applicability of the assay method is illustrated by measurements of single-dose and steady-state plasma levels in clinical experiments, demonstrating the possibility of monitoring plasma levels during at least 24 h after a single dose of 15 mg of Org GB 94. The mean steady-state plasma levels after a daily dose of 3 X 20 mg of Org GB 94 appeared to be remarkably constant with time: 38, 36 and 34 ng/ml after 2, 4, and 6 weeks of treatment of 18 depressed patients.

    2015-01-01

    Online Mendelian Inheritance in Man, OMIM(®), is a comprehensive, authoritative and timely research resource of curated descriptions of human genes and phenotypes and the relationships between them. The new official website for OMIM, OMIM.org (http://omim.org), was launched in January 2011. OMIM is based on the published peer-reviewed biomedical literature and is used by overlapping and diverse communities of clinicians, molecular biologists and genome scientists, as well as by students and teachers of these disciplines. Genes and phenotypes are described in separate entries and are given unique, stable six-digit identifiers (MIM numbers). OMIM entries have a structured free-text format that provides the flexibility necessary to describe the complex and nuanced relationships between genes and genetic phenotypes in an efficient manner. OMIM also has a derivative table of genes and genetic phenotypes, the Morbid Map. OMIM.org has enhanced search capabilities such as genome coordinate searching and thesaurus-enhanced search term options. Phenotypic series have been created to facilitate viewing genetic heterogeneity of phenotypes. Clinical synopsis features are enhanced with UMLS, Human Phenotype Ontology and Elements of Morphology terms and image links. All OMIM data are available for FTP download and through an API. MIMmatch is a novel outreach feature to disseminate updates and encourage collaboration.

    Davies, B. J.

    2013-12-01

    Research into polar science is driven by humanity's pressing concerns about environmental issues and climate change. The effective communication of this science is vital for it to realise its societal and political relevance. However, effective science communication has proved challenging for many reasons, including biased media presentation, lack of time and funds, lack of training, fear of attack by denialists, and poor career credit given for outreach and education work. A key question is how time-poor researchers, whilst working in full-time academic positions, can implement effective outreach strategies with little budget and few resources, that satisfies not only their personal desire to publicise and communicate their work, but also the demands of their research funder. Science websites and blogs offer one possibility, but there is little critical evaluation as to their effectiveness. The aim of this work is to evaluate a website and social medial tools written by an academic that was established to communicate peer-reviewed science. The goal of www.AntarcticGlaciers.org is to communicate key scientific concepts and to deliver new research findings via a professional, attractive, website and blog, supported by a strong social media presence. The objectives were to 1) to clearly explain and illustrate key concepts in glaciology as well as the latest developments in Antarctic research; 2) to be well aligned with national school curriculums, and to support school and university learning; 3) to include interactive features and social networking tools to encourage engagement and discourse; 4) to be aware of and well aligned with the website's intended audience. One year after website launch, the website was evaluated using a combination of an online feedback form, Google Analytics and analysis of Twitter followers. Our analysis shows that just one year after launch the website is a useful information resource, with some aspects that do challenge the knowledge

    2010-03-01

    Full Text Available Abstract Background The ancestry of mitochondria and chloroplasts traces back to separate endosymbioses of once free-living bacteria. The highly reduced genomes of these two organelles therefore contain very distant homologs that only recently have been shown to recombine inside the mitochondrial genome. Detection of gene conversion between mitochondrial and chloroplast homologs was previously impossible due to the lack of suitable computer programs. Recently, I developed a novel method and have, for the first time, discovered recurrent gene conversion between chloroplast mitochondrial genes. The method will further our understanding of plant organellar genome evolution and help identify and remove gene regions with incongruent phylogenetic signals for several genes widely used in plant systematics. Here, I implement such a method that is available in a user friendly web interface. Results OrgConv (Organellar Conversion is a computer package developed for detection of gene conversion between mitochondrial and chloroplast homologous genes. OrgConv is available in two forms; source code can be installed and run on a Linux platform and a web interface is available on multiple operating systems. The input files of the feature program are two multiple sequence alignments from different organellar compartments in FASTA format. The program compares every examined sequence against the consensus sequence of each sequence alignment rather than exhaustively examining every possible combination. Making use of consensus sequences significantly reduces the number of comparisons and therefore reduces overall computational time, which allows for analysis of very large datasets. Most importantly, with the significantly reduced number of comparisons, the statistical power remains high in the face of correction for multiple tests. Conclusions Both the source code and the web interface of OrgConv are available for free from the OrgConv website http

    Full Text Available Introducción: El nitrógeno es el nutriente más demandado por los árboles de nogal pecanero, por lo que es considerado un factor limitante para su desarrollo, producción y calidad de la nuez. Sin embargo, ante el aumento en el precio de los fertilizantes y sus efectos adversos en el ambiente, actualmente es más evidente la necesidad de aplicar nutrientes de manera sustentable. Una alternativa para disminuir la aplicación de fertilizantes nitrogenados inorgánicos en nogal pecanero, es complementarlo con composta, humus de lombriz, lixiviado de lombriz y microorganismos potenciadores de la fertilidad del suelo, como son las micorrizas, entre otros. Por lo que el objetivo del estudio fue reducir la aplicación de nitrógeno inorgánico al suelo mediante la adición de enmiendas orgánicas y microorganismos potenciadores de la fertilidad del suelo sin afectar producción ni calidad. Método: El estudio se realizó en el municipio de Aldama, Chihuahua, durante los ciclos 2010-2012 en árboles ‘Western Schley’, se utilizó una estructura Taguchi L16 para cuatro factores y cuatro niveles para cada factor: nitrógeno 330, 220, 110 y 0 kg ha-1; composta 0, 2.5, 5.0, 7.5 t ha-1; humus de lombriz (OptiHumusMR 0, 1.5, 3.0, 4.5 t ha-1 y micorrizas (Sehumic-VamMR 0, 7.5, 15.0, 22.5 g pulg-1 de tronco. Se determinó el contenido de materia orgánica y nitratos en el suelo, producción y calidad de la nuez, los cuales se analizaron por superficie de respuesta. Resultados: A pesar de que para producir 2.9 t ha-1 se logró reducir la aplicación de nitrógeno, este nivel no permitió obtener una buena calidad de la nuez ni alcanzar un contenido adecuado de materia orgánica y nitratos en suelo. Para un rendimiento de 2.9 t ha-1 con 153 nueces kg-1 y 59.4% de nuez comestible, 1.06% de materia orgánica y 183 ppm de nitratos en suelo se requirieron 305 kg de N, 6600 kg de composta, 3500 kg de humus de lombriz y 18 g de micorrizas por pulg-1 de tronco

Se presenta el caso de una mujer de 49 años de edad que, tras padecer un infarto cerebral, presentó una transformación de su personalidad y de sus valores previos. Anteriormente era una persona con múltiples miedos, cuidadosa, metódica en su vida diaria. Tras el infarto comenzó a presentar conductas de provocación y una mayor desinhibición e impulsividad, menor tolerancia a la frustración, así como mínima capacidad de planificación y resolución de problemas. Además, fue incapaz de conservar ningún trabajo y perdió las relaciones sociales. Se realizaron estudios de imagen (tomografía computarizada (TC y resonancia magnética (RM, electroencefalograma (EEG y una evaluación neuropsicológica. Los resultados obtenidos son compatibles con un trastorno orgánico de la personalidad subtipo desinhibido, caracterizado clínicamente por la tendencia a la labilidad emocional, la desinhibición conductual y la falta de control de impulsos. El trastorno orgánico de la personalidad es una afectación crónica e irreversible que está influyendo en la capacidad de autogobierno de la paciente, y por ello deben valorarse los aspectos psiquiátrico-forenses pertinentes.

    Full Text Available A bananicultura apresenta importância social na geração de emprego e renda e como fonte alimentar para pessoas em todo o mundo. A crescente demanda por frutos de alta qualidade tem contribuído para a conversão de áreas manejadas convencionalmente para sistemas de manejo orgânico. Contudo, inexistem informações seguras referentes às vantagens de cada tipo de manejo, que possam subsidiar os agricultores nessa importante tomada de decisão. Assim, com o objetivo de comparar cultivares de bananeira, em manejo convencional e orgânico, foram avaliadas as características agronômicas e o estado nutricional das bananeiras, quantificando-se o teor de minerais nas folhas. Foram avaliadas as cultivares Caipira (AAA, Maravilha (AAAB, Pacovan Ken (AAAB, Prata-Anã (AAB, Thap Maeo (AAB e Tropical (AAAB. Os dados foram submetidos à análise de variância, e as médias, comparadas pelos testes Scott Knott e Tukey, a 5% de probabilidade de erro. O sistema de cultivo afetou os parâmetros agronômicos de bananeira, destacando-se a cultivar Thap Maeo, que apresentou superioridade para algumas características agronômicas, podendo ser facilmente utilizado em sistema orgânico de cultivo. As cultivares apresentaram diferenças agronômicas, independentemente do sistema de manejo adotado. O tipo de manejo afeta a maioria das variáveis, exceto para peso do cacho, peso total da penca, número de frutos por penca, despencamento e firmeza do fruto com casca.

    Full Text Available No estudo da serapilheira nos solos de mata do Arenito Bauru foram feitas as seguintes observações: Elaborou-se uma nomenclatura específica, dada a carência de termos técnicos em português, para denominar as diferentes camadas que constituem os horizontes orgânicos das matas. A matéria orgânica nos horizontes A00 e A0 foi determinada pelo processo de perda ao rubro e não pela multiplicação do teor de carbono por 1,724, porque, na serapilheira, este último processo conduz a resultados menos exatos. Apesar de não coincidirem exatamente as coletas de serapilheira com a dos perfis do levantamento pedológico já efetuado anteriormente no local, a sua associação permitiu esboçar o estado da matéria orgânica nestes solos. A quantidade de matéria orgânica da serapilheira oscila entre 1/2 a 1 da quantidade contida nos primeiros 30 cm do solo (camada a. O emprêgo do fogo para eliminar os restos vegetais das matas recém-derrubadas ou dos restos de cultura, é prática condenável em qualquer tipo de solo, mas, neste, assume aspecto ainda mais grave. Pelo estudo do fracionamento da matéria orgânica das diferentes camadas, constatou-se decomposição muito intensa, mesmo para a lignina, que é a base das substâncias humificadas. Como o levantamento pedológico já havia indicado, estes solos são pobres em substâncias orgânicas, mesmo no início da sua exploração agrícola. O estudo do fracionamento das substâncias nitrogenadas indica um enriquecimento do nitrogênio protéico, quando comparado com a matéria orgânica total. Deve haver perdas de nitrogênio, porém, muito menores que as das substâncias não nitrogenadas. A concentração, das frações nitrogenadas, à medida da evolução da matéria orgânica, é muito grande, caindo a relação C/N de, aproximadamente, 21-30 na camada L a 10-14 na camada a.The results of the study of a forest floor of Arenito Bauru Soil are summarized as follows: The organic matter

  16. Dynamics and Preservation Potential of Subduction Complexes in Continental Sutures: A Case Study from the Sedimentary-Marix Mélange of the Indus-Yarlung Suture Zone in Southern Tibet

    Intra-continental sutures are the geologic record of ancient subduction zones. Subduction complexes are a useful record of ancient continental collisions because they preserve sediments and/or blocks from units which have since eroded and are the first point of contact during collision. The India-Asia collision is one of the most-studied collisional orogens, but how much of the original subduction complex is preserved and what we can determine about the dynamics of the ancient subduction zone along the southern margin of Asia is poorly understood. Compared to other subduction complexes around the world, the complex preserved in the Indus Yarlung Suture Zone (IYSZ) of southern Tibet is anomalous. Blueschist facies metamorphism, a prominent mineral assemblage along intra-continental suture zones, is common in the northwest Himalaya, but not found along the central segment of the IYSZ. Most of the subduction complex is greenschist facies, inconsistent with the geotherm for a subduction zone. We present a metamorphic history for the greenschist facies rocks to reconcile this contradiction. A deep forearc basin (~5-8 km) developed during the Cretaceous, requiring an accretionary subduction zone, a topographic or structural outer forearc high behind which to trap sediment, and/or basal subduction erosion. The preserved subduction complex is almost entirely tectonic sedimentary-matrix mélange with minor outcrops of overlying turbidites. We present evidence from detrital zircon U-Pb geochronology of sandstones that indicate along-strike variability in the provenance of the sedimentary-matrix mélange. For example, both lower and upper plate material are present near the town of Ngamring, while regions along-strike to the west contain little to no upper plate material. The blocks in the sedimentary-matrix mélange are well-mixed throughout kilometers of exposed width.

    En la década de los años sesenta la Armada acometió un proceso de organización que fue en su momento un auténtico modelo e incluso referencia válida para otras instituciones. Desde entonces, los cambios experimentados en todos los ámbitos han sido tales y tan rápidos, que su reflejo en la Organización de la Armada revelaba que era necesario un proceso de revisión. Desde 1997, la Comisión de Estudios de la Armada (COMESAR viene trabajando en este sentido y ya se han abordado modificaciones y reestructuraciones para adaptarse a los cambios producidos. En este artículo se recogen los estudios realizados para la aplicación en todos los niveles de la Armada de los cinco enfoques orgánicos en que se basa la nueva organización -los procesos de trabajo, la estructura, las personas, la tecnología, y el entorno-, y su progresiva implantación en la estructura orgánica de la Armada.

    We used isolated chicken retina to induce spreading depression by the glutamate receptor agonist N-methyl-d-aspartate. The N-methyl-d-aspartate-induced latency time of spreading depression was extended by the glycine(B) binding site competitive antagonist 7-chlorokynurenic acid. Addition of the glycine transporter type-1 inhibitors NFPS and Org-24461 reversed the inhibitory effect of 7-chlorokynurenic acid on N-methyl-d-aspartate-evoked spreading depression. The glycine uptake inhibitory activity of Org-24461, NFPS, and some newly synthesized analogs of NFPS was determined in CHO cells stably expressing human glycine transporter type-1b isoform. Compounds, which failed to inhibit glycine transporter type-1, also did not have effect on retinal spreading depression. These experiments indicate that the spreading depression model in chicken retina is a useful in vitro test to determine activity of glycine transporter type-1 inhibitors. In addition, our data serve further evidence for the role of glycine transporter type-1 in retinal neurotransmission and light processing.

  4. Geochemistry of jadeitites and jadeite-lawsonite rocks in a serpentinite mélange (Rio San Juan Complex, northern Dominican Republic): Constraints on fluid composition in a subduction channel environment

    2010-05-01

    Jadeitites are excellent rock types for obtaining information on fluid composition in subduction zones. Recent studies indicate that many jadeitites appear to have formed by direct precipitation from a fluid [1]. In almost all localities worldwide (see e.g. Harlow and Sorensen, 2005) jadeitites are found either as allochthonous blocks or as veins and lenses directly within the serpentinite country rock of serpentinite mélanges. In the Rio San Juan Complex on the other hand jadeitite also frequently occurs as veins (cm to some dm in thickness) within lawsonite-blueschist blocks [2,3,4] entrained in the serpentinite mélange. The mélange of the Rio San Juan Complex also contains blocks (m to 10m scale) of different metamorphic grade and lithology (eclogites, blueschists, orthogneisses and very low grade rocks) showing contrasting but interrelated P-T-t paths. The consistency of such interrelated P-T-t paths with those obtained by numerical models led Krebs et al. [5] to interpret the mélange of the Rio San Juan Complex as a former subduction channel. So far, two types of jadeitite have been found in the blueschist blocks: either as discordant veins cutting the foliation, or as concordant layers. In some cases the jadeitites contain large amounts of lawsonite and should then better be called jadeite-lawsonite rocks. The latter rock type may form a network of thin (nephrite and jadeitite) and serpentinite: Metasomatic connections.

    Based on the historical data that are extracted from a time series of satellite images, SLEUTH has been employed to simulate the urban growth and land use evolution in Jing-Jin-Lang area. To make SLEUTH applicable to Jing-Jin-Lang area,a number of calibrations should be done for the model. After calibrations,SLEUTH is used for "backcasting" of urban extent and land use/cover change with spatiotemporal interpolation during 1 985 to 2008.The simulated results are analyzed with historical data. On this basis, SLEUTH used as a forecasting tool to simulate the process of LUCC during 2009 to 2020 respectively. Using SLEUTH model, urban growth tendency in future was forecasted. The results indicated that, margin growth occupied dominant station relative to other growth method. In future, it was going to grow outward continually taking old urban area as the center all the same. At the same time, it was traffic system nowadays that was going to have an important influence to urban development in Jing-Jin-Lang area. At last, through using qualitative and quantitative method,urban expansion driving factors were discussed. Natural environment, national macroscopic policy regulation,traffic, development zone construction and special factors were important to urban growth in Jing-Jin-Lang area.The principal component analysis showed that, population-culture-economy factor and economy factor and economy-environment factor was respectively the first principal component to influence urban growth in Beijing and Tianjin and Langfang.%利用遥感和CIS技术获取历史数据,采用SLEUTH模型,对京津廊坊地区城市增长和土地利用演化进行模拟.模拟过程中,通过获取模型对于城市土地利用演化模拟的最佳模型参数系列.实现SLEUTH模型的本地化,重建了研究区1985-2008年城市土地利用历史动态演化过程,并模拟其未来动态扩展趋势,为研究区城市发展和城市规划提供科学依据.最后.通过对社会经济驱

    Full Text Available Sous haute pression, les propriétés thermodynamiques et les équilibres de phase sont généralement évalués en appliquant la même équation d'état aux phases en présence. Les règles de mélange déterminent la variation des paramètres avec la composition. L'extension de ces méthodes à des systèmes polaires exige une révision de ces règles. Une seconde difficulté se présente si on applique une équation d'état contenant plus de deux paramètres. Les relations existant entre les grandeurs d'excès et les règles de mélange apportent une solution aux problèmes ainsi définis. Les exemples proposés portent sur la prédiction des équilibres de phase de systèmes ternaires, l'application du concept de contributions de groupes et l'utilisation d'une équation d'état contenant quatre paramètres. Under high pressure, thermodynamic properties and phase equilibria are generally evaluated by applying the same equation of state to the phases present. Mixing rules determine how parameters vary with the composition. The extension of such methods to polar systems requires these rules to be revised. A second difficulty arises if an equation of state containing more than two parameters is used. The relations existing between excess functions and mixing rules provide a solution to the problems thus defined. The examples proposed concern the predicting of phase equilibria for ternary systems, the application of the concept of group contributions and the use of an equation of state containing four parameters.

    Petrological and geochronological data of high pressure (HP) rocks from Cuba and Dominican Republic indicate continuous subduction in the northern edge of the Caribbean since ca. 120 Ma. However, expected correlation of the associated subduction zone towards the west in Guatemala is uncertain, for similar HP rocks in this region have metamorphic ages as old as 150 Ma. In this contribution we present new geochemical and U-Pb/Lu-Hf ages of HP rocks from the Escambray terrane and the central Cuba serpentinite mélange that allow geodynamic correlations between the Greater Antilles and Guatemala during the early and late Cretaceous. The Escambray composite terrane constitutes a metamorphic accretionary complex containing oceanic and platform-derived metasedimentary and metaigneous rocks that were tectonically assembled in the Caribbean subduction environment during the latest Cretaceous. The complex crops out as two domes, named Trinidad to the west and Sancti Spiritus to the east, forming a tectonic window below the arc-related Mabujina amphibolite complex and the allochthonous Cretaceous volcanic arc terrane. The latter overrides the central Cuba mélange, which contains low-pressure ophiolitic blocks and HP blocks of eclogite, garnet amphibolite and blueschist facies rocks within a serpentinitic matrix. This serpentinite mélange and similar melange bodies within the Escambray complex have been interpreted as fragments of the Caribbean subduction channel. The studied HP samples are of basaltic composition, poor in K2O (<0.34 wt %) and Rb (< 3.05 ppm), relatively rich in Ta (0.07-0.77 ppm) and Hf (0.74-4.17 ppm), and rich in Nb (0.68- 13.53 ppm). Most samples show a REE chondrite-normalised patterns characterized by a subtle LREE depletion, except a few samples which are characterized by slight enrichment in LREE. Based on their distinctive trace-element contents, most of the basaltic protholiths of the samples are identified as E- to N-MORB signature. Some samples

    Full Text Available De acordo com a estratégia de seleção e o ganho que ela proporcionará, pode-se orientar, de maneira mais efetiva, um programa de melhoramento, bem como predizer o sucesso do esquema seletivo adotado. O objetivo deste trabalho foi verificar a estabilidade das relações entre caracteres fenotípicos a partir de populações de cenoura cultivadas em sistemas de produção orgânico e convencional. Os experimentos foram conduzidos na Embrapa Hortaliças, DF. Duas populações de cenoura em fase de melhoramento e quatro cultivares comerciais foram plantados em novembro de 2007 no campo nos dois sistemas de produção, com delineamento de blocos casualizados com quatro repetições e parcelas de 1 m², com 100 plantas por parcela. Aos 90 dias após o semeio, 20 raízes por parcela foram colhidas e avaliadas para caracteres fenotípicos. Foi realizada análise de variância com determinação da interação entre tratamentos e sistemas de produção, correlações fenotípicas, análise de trilha e os ganhos com as seleções direta e correlacionada. Observouse que a quase totalidade das correlações medianas acima de 0,30, bem como os maiores efeitos diretos da análise de trilha e os maiores ganhos diretos e indiretos estimados, foi repetida nos dois sistemas, indicando que eles foram muito semelhantes na expressão da relação entre os caracteres. Assim, o melhoramento visando aos caracteres avaliados não precisa ser realizado em ambas as áreas de cultivos orgânico e convencional.

    Full Text Available Chromium and its compounds give toxic and/or hazardous characteristics to all those industrial wastes, solids or liquids, that contain them. Organic solvent extraction is a technique that allows the recovery of chromium contained in these residues. In this work the extraction of Cr(III from aqueous solutions with solutions of a cationic reactive (DEHPA in kerosene is studied. In the same way the stripping process was studied. It has been found that Cr(III and DEHPA react in a 1/1 molar ratio, being the extraction kinetics very fast. Final aqueous phase final pH influence extraction yield, so that it is necessary to work with pH values between 3 and 4. It must be added a modifier (isodecanol to the organic phase to avoid the formation of a third phase in the stripping process. The concentration of isodecanol has to be higher than 15 %, so the organic phase used was a solution of 12.5 % v/v DEHPA in kerosene and 20 % v/v isodecanol. The stripping process is slow and must be carried out in an oxidant alkalyne medium, thus an aqueous solution of NaOH and H2O2 was used. An increase in the concentration of NaOH and H2O2 leads to an increase in the stripping yield initially, and becomes stable when concentrations of NaOH and H2O2 used are higher than 0.45 N and 4 % v/v respectively.

    El cromo y sus compuestos confieren un carácter tóxico y/o peligroso a los residuos industriales, sólidos o líquidos, que los contienen. Una técnica que permite recuperar el cromo existente en estas sustancias es la extracción con disolventes orgánicos. En el presente trabajo se estudia la extracción del Cr(III presente en disoluciones acuosas con disoluciones de un reactivo de carácter catiónico (DEHPA en queroseno. Igualmente se estudia el proceso de reextracción. Se ha encontrado que el Cr(III y el DEHPA reaccionan mol a mol, siendo la cinética de extracción muy rápida. El pH final de

    On March 17, 2015, a geomagnetic storm—the largest of the solar cycle to date— hit Earth and gave many sky watchers around the world a beautiful auroral display. People made thousands of aurora-related tweets and direct reports to Aurorasaurus.org, an interdisciplinary citizen science project that tracks auroras worldwide in real-time through social media and the project's apps and website. Through Aurorasaurus, researchers are converting these crowdsourced observations into valuable data points to help improve models of where aurora can be seen. In this presentation, we will highlight how the team communicates with the public during these global, sporadic events to help drive and retain participation for Aurorasaurus. We will highlight some of the co-produced scientific results and increased media interest following this event. Aurorasaurus uses mobile apps, blogging, and a volunteer scientist network to reach out to aurora enthusiasts to engage in the project. Real-time tweets are voted on by other users to verify their accuracy and are pinned on a map located on aurorasaurus.org to help show the instantaneous, global auroral visibility. Since the project launched in October 2014, hundreds of users have documented the two largest geomagnetic storms of this solar cycle. In some cases, like for the St. Patrick's Day storm, users even reported seeing aurora in areas different than aurora models suggested. Online analytics indicate these events drive users to our page and many also share images with various interest groups on social media. While citizen scientists provide observations, Aurorasaurus gives back by providing tools to help the public see and understand the aurora. When people verify auroral sightings in a specific area, the project sends out alerts to nearby users of possible auroral visibility. Aurorasaurus team members around the world also help the public understand the intricacies of space weather and aurora science through blog articles

    Full Text Available El objetivo del presente trabajo fue evaluar la resistencia de suelos orgánicos del noreste argentino, una vez cumplido el proceso de estabilización con distintas resinas. Se realizaron ensayos de resistencia triaxial sobre probetas de suelo orgánico, natural y estabilizado. El tratamiento se materializó incorporando al suelo resinas en las que intervinieron productos obtenidos de la cadena de fabricación del tanino de Quebracho Colorado, un aldehído y agua. La concentración de la resina fue variable, como también la proporción con respecto al peso seco del suelo en que se la agregaba y los días de curado. Los ensayos triaxiales permitieron el trazado de las líneas de resistencia intrínseca para evaluar la acción del estabilizante. Los resultados indicaron un incremento en la resistencia mecánica del suelo estabilizado, pudiéndose identificar la resina que indujo a un mejor efecto sobre el suelo natural, permitiendo extender las posibilidades de aplicación del material tratado.The aim of this work was evaluating the strength of organic soils in northeastern region of Argentina after completing the stabilization process with different types of resins. Several triaxial essays on probes of organic, natural and stabilized soils, were carried out. Treatment was materialized by adding resins to soil, in wich products obtained in the chain of production of tannin from “Quebracho Colorado”, an aldehyde and water took part. Concentration of resin was variable, as well as rate of dry weight of soil in wich it was added and the curing time. Tri - axial tests allowed drawing of intrinsic strength lines in order to evaluate the action of stabilizer. Results indicated a rise of mechanical strength of stabilized soil, allowing identification of resin wich induced a better effect on natural soil and to extend possibilities of application of treated material.

    A team of educators, scientists, and communication experts from multiple universities as well as a Science museum will report on the impact of ScienceToGo.org, which is an Out of Home Multi-Media (OHMM) exhibit targeting adults riding a major subway system. The campaign's goal is to design, implement, and study the efficacy of an OHMM model for free choice science learning about our changing climate. Subway riders represent a diverse and captive audience with most of them spending an average of one hour a day in the subway system. Through the use of specially designed OHMM such as train placards, platform posters, and virtual resources the campaign engages a potential audience of 500,000 riders/day with opportunities to learn climate change science informally. The primary goal of the ScienceToGo.org campaign is to engage, entertain, and educate the adult subway riding community in major U.S. city about climate change as a real, relevant, and solvable local challenge. A naturalistic quasi-experimental inquiry employing a mixed methodology approach best describes our research design with half of the subway system exposed to the project signage (experimental group) and the other half not being exposed to the project signage (control group). To identify possible outcomes, data was collected in the several forms: survey, analytic data associated with website, social media, web app, focus groups, and observations. This campaign is an example of how an individual's daily routine may be enhanced with an informal science learning opportunity. We see an urgent need to improve both the public's engagement with climate change science and to the profile of climate change science in formal education settings. The campaign makes deliberate use of humor and fun to engage a public and diverse audience with the serious issue of climate change. The research that will be presented will reveal some of the strengths and weaknesses of this strategy when communicating science to a diverse

    Full Text Available The corrosion of copper in the presence of volatile organic acids is frequent. Thus, for example, it is known that failures by corrosion of the copper tubes take place in the air conditioning equipment, caused by volatile organic acids emitted by oils used in their manufacturing. Another frequent case is the corrosion of copper objects caused by the acids emitted by the materials used in packing, wood and resins, amongst others. This communication presents the corrosion results of copper exposed to 100% relative humidity and different concentrations (10-300 ppm of formic [HCOOH], acetic [CH3COOH], propionic [CH3CH2COOH] and butyric [CH3(CH22COOH] acid vapours, for short exposure times. The techniques used were gravimetric analysis, scanning electron microscopy (SEM and X-ray diffraction (XRD.

    Full Text Available Entre las docenas de compuestos orgánicos aromáticos que conforman una parte de la contaminación en el ambiente de una ciudad, el naftaleno es un compuesto orgánico semi-volátil (COS presente en una buena concentración. El naftaleno o también llamado naftalina es un sólido blanco que se evapora fácilmente y se produce naturalmente cuando se queman combustibles, también cuando se quema tabaco o madera se produce naftalina. La exposición a grandes cantidades puede dañar o destruir una porción de los glóbulos rojos. Esto puede hacer que el número de glóbulos rojos disminuya hasta que su cuerpo remplace las células destruidas. Esta condición se llama anemia hemolítica. Se han descrito numeroso casos de anemia hemolítica en niños, incluso en recién nacidos, ya que la naftalina puede pasar de la sangre de una mujer embarazada a la sangre del feto. En este trabajo, se ha seleccionado el naftaleno como molécula modelo porque da un espectro Raman con picos bien definidos en un rango entre 500 y 3000 cm-1. La espectroscopia Raman de superficie promovida (SERS se usó para la detección de unos cuantos micro-gramos de naftaleno adsorbido sobre papel filtro modificado. La modificación consistió en aplicar un recubrimiento de nano-partículas de Ago sobre el papel usando dos métodos en los cuales se realiza una reacción química de reducción de un compuesto de plata. Al aplicar ésta técnica espectroscópica usando solo papel filtro se determina una cantidad mínima detectable por Raman convencional. Este valor cmd encontrado para el naftaleno, se toma como referencia para probar bajo la misma metodología, papel filtro con recubrimiento de nano-partículas de Ago. Bajo la técnica SERS la señal de los picos detectados fue mucho mayor, posibilitando la cuantificación de este contaminante atmosférico en cantidades menores al cmd encontrado

    How can an informal science learning project about climate change facilitate alliances among unlikely parties? We found a sweet spot of collaboration among private, public, and the non-profit sectors by borrowing strength and leveraging common interests. Using mass transit and out of home media, we created a diverse community around a learning campaign that starred an ostrich named "Ozzie." In 2013-14, ScienceToGo.org ran a series of 12 engaging posters and placards staring 'Ozzie the Ostrich' on the Massachusetts Bay Transit Authority's Red and Orange subway lines targeting a daily audience of 400,000+ riders. The curriculum was divided into three phases: reality, relevance, and hope. Phase I established the reality of climate change (3 months). Phase II helped T-riders appreciate the relevancy of climate change to the local environment of Boston (4 months). Phase III engaged Bostonians with an array of hopeful examples of how people, companies, and organizations are effectively creating a more sustainable future (5 months). The focus of this presentation will be on the relationships that emerged from the work that went into Phase III. Engaging urban populations with climate change science is a difficult challenge since cities seem so removed from the 'natural environment.' However, mass transit provides an inherent means of communicating environmental messages with a cross section of the urban population. Our team felt that any messaging curriculum for an urban subway system must complement the scary reality of a changing climate with hopeful solutions that exist for dealing with it effectively. Urban areas such as Boston must develop adaptation and mitigation strategies that will help them not only survive, but thrive in a changing environment. Making our audience aware of the amazing efforts in this area was the goal of Phase III. There were three parts to our efforts: the signage on the subway, above ground ostriches, and social events.

    Full Text Available Em solos tropicais, a disponibilidade de fósforo (P pode ser regulada pela decomposição e mineralização da fração lábil de P orgânico (Po, tornando necessários estudos para saber a sua real contribuição no solo. O objetivo deste trabalho foi avaliar o teor de Po total e lábil em horizontes superficiais de diferentes classes de solo e quais as propriedades do solo exercem controle na acumulação dessas frações de P. Foram estudadas amostras de diferentes horizontes diagnósticos superficiais, a saber: H e O hístico; A chernozêmico; e A húmicos, coletados em vários estados do Brasil. Para a determinação das frações totais de P inorgânico (Pi e orgânico (Po, foi usado o método da extração-sequencial ácido-alcalina, e a fração lábil de P foi determinada pela extração com bicarbonato de sódio. A taxa de recuperação de Pi + Po em relação à extração nítrico-perclórica do P total (PT variou de 46 a 99 %. O Po total variou entre 35 e 1077 mg kg-1, com uma média de 298 mg kg-1. Para a fração lábil do Po, os teores variaram entre 7,2 e 99,5 mg kg-1, com uma média de 27,1 mg kg-1. O Po variou, em média, de 36 a 46 % do P total extraído. Em relação ao P lábil, o Po representou mais de 70 % para todos os horizontes diagnósticos. O PT foi o principal atributo controlador da acumulação de Po nos solos pelas análises de correlação e regressão múltipla. Verificou-se que horizontes com baixa capacidade de adsorção de P proporcionaram alta labilidade de Po.

    Ophiolite, as a well record of ocean-crust relic, plays an important role in the study of paleo-plate tectonics and its evolution. The newly-found Tuerkubantao ophiolitic mélange is located in the south of the Buerjin, Altay area, China. It is composed of ultramafic rock, gabbro, diabase, basalt and flysch formation. The zircon U-Pb ages of the gabbro and gneissic granite are 363 Ma and 355 Ma, respectively. It suggests that the generation of the ophiolite and ocean-crust subduction was at the end of the Late Devonian. The geochemical characteristics of ultramafic-mafic rocks and basalt suggest tbat they may belong to low alkali, low Ti and Mgrich tholeiite series and that the basalt may have been formed in MORB-like tectonic setting. The gneissie granite in the mélange belt may belong to sodium or low-K series and occurred in volcanic arc or syn-collision tectonic setting that was also related with the ocean-crust subduction. Tuerkubantao ophiolite, together with Kekesentao, Qiaoxiahala anc Buergen ophiolites constitute an ophiolitic mélange belt along the Irtys fault, which belongs to the Zaysan-Kekesentao-South Mongolia geosuture zone dividing the Siberian plate from the Kazakhstan-Junggar plate.%蛇绿岩作为残留洋壳的良好记录,对于研究古板块构造及其演化具有重要意义.新发现的吐尔库班套蛇绿混杂岩位于新疆阿尔泰布尔津南部,主要由超镁铁岩、辉长岩、辉绿岩、玄武岩、复理石建造等构成.其中辉长岩和片麻状花岗岩的锆石U-Pb年龄在363~355 Ma,指示蛇绿岩的形成、洋壳俯冲时代在晚泥盆世晚期.岩石地球化学特征表明,该蛇绿岩套的镁铁-超镁铁岩和玄武岩属低碱、低钛、富镁的拉斑玄武岩系列,具有较典型的幔源岩石特征,玄武岩形成于类似洋中脊的构造环境.混杂岩带中的片麻状花岗岩属于钠质的低钾岩石系列,形成于火山孤或同碰撞构造环境,亦为洋壳俯冲的结果.吐尔库班

Compararam-se o sistema orgânico (SO e o convencional (SC de tomates da variedade Débora e Santa Clara, por meio de um estudo interdisciplinar. O experimento foi conduzido em blocos casualizados com seis repetições, com parcelas medindo 25 ´ 17 m, em um Argissolo Vermelho-Amarelo distrófico. Todas as práticas culturais foram realizadas de acordo com as técnicas utilizadas pelos agricultores convencionais ou orgânicos da região. No SO a fertilização foi realizada aplicando, em cada cova, composto orgânico, superfosfato simples e calcário dolomítico (5 L, 60 g e 60 g e pulverizando biofertilizante duas vezes por semana. No SC, foi utilizado 200 g 4-14-8 (NPK por cova e, após o plantio, 30 g N, 33 g K and 10,5 g P por cova; a partir de 52 dias após o plantio, as plantas foram pulverizadas com adubo foliar uma vez por semana. No SC, para o controle dos problemas fitossanitários, foram realizadas aplicações de mistura de inseticidas, fungicidas e acaricidas duas vezes por semana. Para o SO o controle foi realizado pulverizando-se extratos de pimenta-do-reino, de alho e de eucalipto; calda bordaleza e biofertilizante duas vezes por semana. O vira-cabeça foi a principal doença do SO, resultando em menor desenvolvimento de plantas, número de inflorescência e produção. No SC, a doença foi mantida sob controle, sendo que a população de tripes, vetor do vírus, ocorreu em níveis inferiores que no SO. A variedade Santa Clara apresentou maior incidência da virose e, por esse motivo, teve desempenho inferior à Débora, especialmente no SO. A ocorrência de Liriomysa spp. foi significativamente menor no SO, possivelmente devido à maior freqüência de Chrysoperla. O SC apresentou menor incid

    The utilization of biology research resources, coupled with a “learning by inquiry” approach, has great potential to aid students in gaining an understanding of fundamental biological principles. To help realize this potential, we have developed a Web portal for undergraduate biology education, WormClassroom.org, based on current research resources of a model research organism, Caenorhabditis elegans. This portal is intended to serve as a resource gateway for students to learn biological concepts using C. elegans research material. The driving forces behind the WormClassroom website were the strengths of C. elegans as a teaching organism, getting researchers and educators to work together to develop instructional materials, and the 3 P's (problem posing, problem solving, and peer persuasion) approach for inquiry learning. Iterative assessment is an important aspect of the WormClassroom site development because it not only ensures that content is up-to-date and accurate, but also verifies that it does, in fact, aid student learning. A primary assessment was performed to refine the WormClassroom website utilizing undergraduate biology students and nonstudent experts such as C. elegans researchers; results and comments were used for site improvement. We are actively encouraging continued resource contributions from the C. elegans research and education community for the further development of WormClassroom. PMID:17548872

  10. Effects of early compost application on no-till organic soybean Resposta à antecipação da adubação com composto orgânico na soja orgânica em plantio direto

    Full Text Available Weed control has always been an important issue in agriculture. With the advent of no-till systems, soil erosion was reduced but herbicide use was increased. Organic no-till systems try to adjust reduced erosion to the no use of herbicides. Nevertheless, this adjustment is limited by the cost of mechanical weed control. This cost may be reduced by improved cultural weed control with cover crops mulches. In this paper we report a study on the application of compost manure on an oats winter cover crop, preceding soybean, instead of on the soybean summer crop. Treatments comprised a control without compost manure, and compost manure doses of 4 and 8 Mg ha-1 applied either on oats in winter or soybean in summer, organized in a randomized block design, with five replications. In summer, plots were split into weed-controlled or not controlled subplots. The timing of application and the manure doses did not affect the oats biomass or the soybean performance. However, in summer, without water stress, the application of manure at 8 Mg ha-1 directly on soybean has reduced weed biomass in this crop.O controle de plantas daninhas sempre foi um fator importante na agricultura. Com o advento do plantio direto reduziu-se a erosão do solo, mas houve aumento no uso de herbicidas. O plantio direto orgânico busca conciliar o controle da erosão com a eliminação do uso de herbicidas, porém o custo de produção é onerado pela necessidade de controle mecânico das plantas daninhas. Esse custo poderia ser reduzido por um melhor controle cultural com palhas produzidas por plantas de cobertura no inverno. Neste trabalho, antecipou-se a adubação da soja para a aveia, aplicando na aveia o adubo que seria aplicado na soja, de modo a aumentar a quantidade de palha de aveia sobre a qual a soja seria semeada no verão seguinte. O delineamento experimental foi em blocos ao acaso com parcelas subdivididas. Os tratamentos foram uma testemunha sem adubação e duas doses

  18. Armorican provenance for the mélange deposits below the Lizard ophiolite (Cornwall, UK): evidence for Devonian obduction of Cadomian and Lower Palaeozoic crust onto the southern margin of Avalonia

    Science.gov (United States)

    Strachan, Rob A.; Linnemann, Ulf; Jeffries, Teresa; Drost, Kerstin; Ulrich, Jens

    2014-07-01

    Devonian sedimentary rocks of the Meneage Formation within the footwall of the Lizard ophiolite complex in SW England are thought to have been derived from erosion of the over-riding Armorican microplate during collision with Avalonia and the closure of the Rheic Ocean. We further test this hypothesis by comparison of their detrital zircon suites with those of autochthonous Armorican strata. Five samples analysed from SW England (Avalonia) and NW France (Armorica) have a bimodal U-Pb zircon age distribution dominated by late Neoproterozoic to middle Cambrian (c. 710-518 Ma) and Palaeoproterozoic (c. 1,800-2,200 Ma) groupings. Both can be linked with lithologies exposed within the Cadomian belt as well as the West African craton, which is characterized by major tectonothermal events at 2.0-2.4 Ga. The detrital zircon signature of Avalonia is distinct from that of Armorica in that there is a much larger proportion of Mesoproterozoic detritus. The common provenance of the samples is therefore consistent with: (a) derivation of the Meneage Formation mélange deposits from the Armorican plate during Rheic Ocean closure and obduction of the Lizard Complex and (b) previous correlation of quartzite blocks within the Meneage Formation with the Ordovician Grès Armoricain Formation of NW France.

    2016-05-01

    This study utilizes zircon SIMS U-Pb dating, REE and trace-element analysis as well as oxygen isotope ratios of zircon to distinguish jadeite-rich rocks that formed by direct crystallization from a hydrous fluid from those that represent products of a metasomatic replacement process. Zircon was separated from a concordant jadeitite layer and its blueschist host, as well as from loose blocks of albite-jadeite rock and jadeitite that were all collected from the Jagua Clara serpentinite-matrix mélange in the northern Dominican Republic. In the concordant jadeitite layer, three groups of zircon domains were distinguished based on both age as well as geochemical and oxygen isotope values: age groups old (117.1 ± 0.9 Ma), intermediate (three dates: 90.6, 97.3, 106.0 Ma) and young (77.6 ± 1.3 Ma). Zircon populations from the blueschist host as well as the other three jadeite-rich samples generally match zircon domains of the old age group in age as well as geochemistry and oxygen isotope ratios. Moreover, these older zircon populations are indistinguishable from zircon typical of igneous oceanic crust and hence are probably inherited from igneous protoliths of the jadeite-rich rocks. Therefore, the results suggest that all investigated jadeite-rich rocks were formed by a metasomatic replacement process. The younger domains might signal actual ages of jadeitite formation, but there is no unequivocal proof for coeval zircon-jadeite growth.

    Le prémélange de monensin est utilisé fréquemment sur les fermes laitières canadiennes. L’ingrédient actif de ce produit est le monensin sodique. Bien que son utilisation chez les vaches laitières soit sécuritaire, des cas de surdose ont été rapportés à la suite de consommation de niveaux de monensin plus élevés que ceux recommandés. Un suivi hebdomadaire du pourcentage de matières grasses du réservoir de lait de la ferme devrait être fait de routine suite à la livraison d’aliment médicamenteux contenant du monensin pour détecter rapidement les situations de surdose.

Trabalhando com amostras de compostos, estéreos, resíduos industriais e turfa, discutiu-se a determinação de carbono orgânico através de oxidação pelo íon dicromato. Sugeriu-se que o atual método de determinação de matéria orgânica total por combustão tenha sua utilização restrita ou desaconselhada, devido aos erros grosseiros que proporciona. Como forma de se avaliar a qualidade de materiais orgânicos, discutiu-se a determinação da capacidade de retenção de cátions (CTC em fertilizantes e materiais orgânicos em geral. O grau de maturação ou estabilidade de compostos orgânicos pôde ser convenientemente expresso através da relação entre CTC (meq/l00g e o teor de carbono orgânico expresso em porcentagem.The present paper aimed to study the determination of organic carbon and the cation exchange capacity (CEC of organic materials which can be used as fertilizers. Analytical procedures recommended by Brazilian official methods of fertilizer analysis include the determination of total organic matter by incineration. The errors of this method are not taken into account in spite of the great variability of the organic materials. This paper suggests that the organic characteristics of organic fertilizers must be expressed by the organic carbon content as determined by wet oxidation with dichromate ion and sulfuric acid. There is a great demand for practical indexes for determining the state of composting since the incorporation into the soil of immature organic material can cause severe damage to crops. In order to evaluate the maturity of organic products as manures, compost industrial wastes and peat, the determination of CEC was discussed. It seems possible to define the chemical stabilization of organic materials on the basis of the relationship between CEC and organic carbon

    This paper reports on the partitioning behaviour of 15 perfluorinated compounds (PFCs), including C{sub 4}-C{sub 10} sulfonates and C{sub 5}-C{sub 14} carboxylic acids, between water, sediment and fish (European chub, Leuciscus cephalus) in the Orge River (nearby Paris). Total PFC levels were 73.0 {+-} 3.0 ng L{sup -1} in water and 8.4 {+-} 0.5 ng g{sup -1} in sediment. They were in the range 43.1-4997.2 ng g{sup -1} in fish, in which PFC tissue distribution followed the order plasma > liver > gills > gonads > muscle. Sediment-water distribution coefficients (log K{sub d}) and bioaccumulation factors (log BAF) were in the range 0.8-4.3 and 0.9-6.7, respectively. Both distribution coefficients positively correlated with perfluoroalkyl chain length. Field-based biota-sediment accumulation factors (BSAFs) are also reported, for the first time for PFCs other than perfluorooctane sulfonate. log BSAF ranged between -1.3 and 1.5 and was negatively correlated with the perfluoroalkyl chain length in the case of carboxylic acids. - Research highlights: PFC tissue distribution in European chub followed the order plasma > liver > gills > gonads > muscle. K{sub d} and BAF correlated with PFC alkyl chain length. BSAF negatively correlated with the perfluoroalkyl chain length in the case of carboxylic acids. BSAF did not correlate with alkyl chain length of sulfonates. - Sediment-water, biota-water and biota-sediment partitioning coefficients were determined for perfluorinated acids and sulfonates and were generally correlated with alkyl chain length.

    The Ontological Discovery Environment ( http://ontologicaldiscovery.org ) is a free, public Internet resource for the storage, sharing, retrieval and analysis of phenotype-centered genomic data sets. The intent of this resource is to allow the creation of user-defined phenotype categories based on naturally and experimentally observed biological networks, pathways and systems rather than on externally manifested constructs and semantics such as disease names and processes. By extracting the relationships of complex processes from the technology that produces those relationships, this resource meets a growing demand for data integration and hypothesis discovery across multiple experimental contexts, including broad species and phenotype domains. At a highly processed level, analyses of set similarity, distance and hierarchical relations are performed through a modular suite of tools. The core pivot point of analysis is the creation of a bipartite network of gene-phenotype relations, a unique discrete graph approach to gene-set analysis which enables set-set matching of non-referential data. The central organizing metaphor of a gene set may be created, stored and curated by individual users, shared among virtual working groups, or made publicly available. Gene sets submission incorporates a variety of accession numbers, microarray feature IDs, and gene symbols from model organisms, allowing integration across experimental platforms, literature reviews and other genomic analyses. The sets themselves are annotated with several levels of metadata which may include an unstructured description, publication information and structured community ontologies for anatomy, process and function. Gene set translation to user chosen reference species through gene homology allows translational comparison of models regardless of the face validity of the experimental systems. In addition, computationally derived gene sets can be integrated into phenome interdependency and similarity

    Full Text Available Los compuestos orgánicos fluorados (FOCs o productos químicos perfluorados constituyen un grupo de sustancias utilizadas ampliamente a nivel industrial. El sulfonato de perfluorooctano (PFOS pertenece a este grupo de compuestos y es además el producto de degradación de numerosos FOCs. Este xenobiótico es extremadamente persistente en el medioambiente. Para la población general, las principales vías de exposición a PFOS son: la ingesta alimentaria, la vía inhalatoria y el contacto dérmico. El PFOS se absorbe principalmente por vía oral, se transporta en sangre unido a la albúmina, es capaz de atravesar la placenta y la barrera hematoencefálica y se elimina por vía renal. El principal órgano diana del PFOS es el hígado. Además de los efectos hepatotóxicos y metabólicos observados tras la exposición a este xenobiótico, también están involucrados en sus mecanismos de acción tóxica diversos receptores como son los activadores de proliferación de peroxisomas o PPAR. Al mismo tiempo, presenta inmunotoxicidad, alterando la secreción de citoquinas, la diferenciación celular de monocitos, linfocitos, etc. así como la actividad de las células natural killer. Además, el PFOS es neurotóxico, tanto a nivel central como periférico, e induce importantes alteraciones neuroendocrinológicas en distintos órganos y tejidos que constituyen los ejes hipotalámico-hipofisario-gonadal e hipotalámico-hipofisario-adrenal.

    Full Text Available El aparente conflicto normativo que se presenta entre las normas presupuestales y financieras, descritas en la Ley 30 de 1992 y la disposición contenida en el artículo 4º del Decreto 111 de 1996, Estatuto Orgánico de Presupuesto, debe estudiarse desde la perspectiva de la hermenéutica jurídica, así como desde la autonomía universitaria conferida por mandato constitucional. A partir de las reglas fundamentales para resolver las antinomias jurídicas, el ordenamiento colombiano establece unas reglas generales sobre aplicación normativa contenidas en las Leyes 57 y 153 de 1887. Sin embargo, la determinación concreta de la prevalencia de una norma sobre otra, o mejor, la búsqueda de una interpretación correctiva, requiere de un mayor estudio casuístico. Para el caso de estudio, la autonomía universitaria contemplada en el artículo 69 de la Constitución Nacional requirió que el legislador expidiera la Ley 30 de 1992, que en sus artículos 28 y 57, desarrolló los aspectos en que se refleja la dicha autonomía. El régimen financiero contenido en el capítulo V de la Ley 30 de 1992, es parte esencial del régimen especial de las universidades estatales, pues el legislador consideró que la autonomía universitaria en su dimensión presupuestal, solo se puede garantizar si su presupuesto se mantiene protegido de la libre facultad potestativa del poder ejecutivo.

    Full Text Available O objetivo deste estudo foi avaliar os efeitos dos sistemas de manejo integrado e orgânico sobre atributos de nutrição, sanidade, rendimento e qualidade de maçãs 'Catarina'. O estudo foi realizado em São Joaquim-SC, ao longo das safras de 2008/2009 e 2009/2010. O porta-enxerto era Marubakaido, com filtro de EM-9, e as macieiras conduzidas, em líder central. Os atributos do solo eram adequados ao desenvolvimento e produção das macieiras em ambos os sistemas. O sistema de manejo orgânico aumentou o teor de Cu nas folhas e Ca e Cu na casca e polpa dos frutos, a área de cor vermelha na epiderme dos frutos e a incidência de frutos com queimaduras por sol e com danos por mosca-das-frutas. O índice iodo-amido e o teor de sólidos solúveis foram superiores nos frutos do sistema orgânico. O manejo orgânico reduziu a área foliar média das plantas, e nos frutos reduziu as relações K/Ca, Mg/Ca, N/Ca e (K+Mg/Ca na casca e Mg/Ca na polpa, a severidade de "russeting", o número de sementes e a acidez titulável. Não houve diferenças quanto aos demais atributos avaliados. A produção orgânica de maçãs é viável, desde que disponível tecnologia eficaz para o controle da mosca-das-frutas.

La cuantificación en plasma de los niveles de pesticidas organoclorados (POCs, bifenilos policlorados (PCBs e hidrocarburos aromáticos policíclicos (PAHs se realizó mediante GC-MS. Todas las muestras analizadas presentaron niveles cuantificables de alguno de los COPs incluidos en el estudio. El grupo de COPs que presentó mayores niveles fue el de los PAHs (alcanzando la carga total de PAHs 6,45 ng/ml, siendo el fenantreno el hidrocarburo más frecuentemente detectado y a concentraciones más altas, lo que indica el origen petrogénico de estos contaminantes. La contaminación por PCBs alcanzó niveles menores (3,84 ng/ml, predominando el grupo de los hexaclorobifenilos (PCB-153 y PCB- 138 principalmente. Los niveles de contaminación por POCs fueron también bajos alcanzando valores de 1,67 ng/ml, siendo el principal metabolito del DDT, el p,p´-DDE el compuesto más frecuentemente detectado (89,6% y a más altas concentraciones (0,68 ng/ml. Fue evidente una asociación inversa entre el tamaño de las tortugas y la carga de PCBs y PAHs. Asimismo existieron niveles más altos de contaminación por COPs en los años 2009 y 2010. Este trabajo evalúa por vez primera la presencia de PAHs en sangre de tortugas varadas y nuestros resultados parecen indicar que esta metodología y esta especie animal pueden ser muy útiles para monitorizar la presencia de contaminación por derivados del petróleo en el medio acuático.

    Full Text Available Abstract Background Intellectual disability (ID is a devastating and frequent condition, affecting 2-3% of the population worldwide. Early recognition of treatable underlying conditions drastically improves health outcomes and decreases burdens to patients, families and society. Our systematic literature review identified 81 such inborn errors of metabolism, which present with ID as a prominent feature and are amenable to causal therapy. The WebAPP translates this knowledge of rare diseases into a diagnostic tool and information portal. Methods & results Freely available as a WebAPP via http://www.treatable-id.org and end 2012 via the APP store, this diagnostic tool is designed for all specialists evaluating children with global delay / ID and laboratory scientists. Information on the 81 diseases is presented in different ways with search functions: 15 biochemical categories, neurologic and non-neurologic signs & symptoms, diagnostic investigations (metabolic screening tests in blood and urine identify 65% of all IEM, therapies & effects on primary (IQ/developmental quotient and secondary outcomes, and available evidence For each rare condition a ‘disease page’ serves as an information portal with online access to specific genetics, biochemistry, phenotype, diagnostic tests and therapeutic options. As new knowledge and evidence is gained from expert input and PubMed searches this tool will be continually updated. The WebAPP is an integral part of a protocol prioritizing treatability in the work-up of every child with global delay / ID. A 3-year funded study will enable an evaluation of its effectiveness. Conclusions For rare diseases, a field for which financial and scientific resources are particularly scarce, knowledge translation challenges are abundant. With this WebAPP technology is capitalized to raise awareness for rare treatable diseases and their common presenting clinical feature of ID, with the potential to improve health outcomes

    Full Text Available OBJETIVO: Analisar a demanda e a oferta de alimentos orgânicos para a alimentação escolar no estado de Santa Catarina de acordo com a regulamentação do Programa Nacional de Alimentação Escolar. MÉTODOS: Estudo descritivo e exploratório. No ano de 2010 foi realizado um censo nos 293 municípios do estado por meio de questionário eletrônico para conhecer o percentual de compras de alimentos da agricultura familiar e de alimentos orgânicos. Posteriormente, foram entrevistados in loco alguns atores sociais da alimentação escolar de 52 municípios que compravam alimentos orgânicos da agricultura familiar. Os dados foram apresentados em números absolutos e relativos, com detalhamento por municípios. RESULTADOS: O destino da produção, em sua maioria, foi local e 17,7% dos municípios compraram alimentos orgânicos da agricultura familiar no ano de 2010. Foram relatadas dificuldades tanto do nutricionista quanto dos agricultores familiares e das cooperativas. A maioria dos agricultores e cooperativas não tinha certificação de seus produtos e enfrentava problemas de produção, revelando a necessidade de apoio técnico. Os nutricionistas ressaltaram a falta de certificação de agricultores e a baixa oferta de alimentos orgânicos. Para agricultores e cooperativas, as limitações na comercialização para a alimentação escolar foram a baixa procura por parte dos municípios, as dificuldades no transporte e a sazonalidade da produção. Apesar das dificuldades relatadas, os municípios catarinenses já adquirem frutas, verduras, legumes e outros alimentos. CONCLUSÃO: Os alimentos da agricultura familiar orgânica produzidos localmente, já estão sendo incluídos na alimentação escolar. No entanto, ainda há necessidade de diálogo entre nutricionistas e agricultores familiares.

    2010-05-01

    The general use of pesticides in the Orge Basin, located in the southern part of the Paris suburb (France), is damaging surface water quality. Consequently, an increase in the water supply costs is registered by the water supply agencies that are situated downstream the Orge confluence with the Seine River. In this catchment, high uses of glyphosate are registered for fallow fields (upstream part) and for roadway weed control (downstream part). The proportion of glyphosate coming from these two zones was not well known, along with the double source of its metabolite AMPA originated from the degradation of some detergent phosphonates. The aim of this work was firstly to identify the potential sources of glyphosate and AMPA in urban sectors (such as sewerage system inputs) and in agricultural areas and to quantify the origins of urban pesticides pathways towards surface waters at the basin scale. The new approach of this project was to collect information at three different scales to establish a first step of modeling. At the basin scale, 1 year of surface water monitoring at the outlet of the Orge River was useful to establish the inputs towards the Seine River. At the urban catchment scale, the investigations have permitted to record glyphosate and AMPA loads transferred by storm waters and by wastewaters. Loads were estimated during and out of application calendar, in different hydrological conditions such as rainfall with high intensity or dry conditions. Impact of WWTP on surface water was also demonstrated. The third phase of this work was the interpretation of agricultural inputs from two different agricultural catchments of the Orge River. The results showed the impact of urban uses of glyphosate upon the Orge River contamination with annual loads from 100 times higher from the urban zone than from the agricultural one. Storm sewers were recognized to be the main way for glyphosate transfer towards surface waters. A budget of glyphosate and AMPA inputs and

Ce dernier point conduit à limiter à 35-45 % en masse, la proportion d'alcools C2+ dans le mélange ciblé (fig. 1. Parmi les différents développements précités, IFP et Idemitsu Kosan ont sélectionné des catalyseurs oxydes mixtes à base de cuivre-cobalt ou cuivre-nickel, lesquels conduisent à des performances intéressantes et, notamment, à des alcools en mélange particulièrement purs. Enfin, l'analyse d'ensemble des données IFP et de la littérature ouverte démontre la fatalité de la coproduction parallèle d'hydrocarbures légers. Les principaux résultats sont les suivants : les catalyseurs cuivre-cobalt, fondés sur des systèmes oxydes mixtes alcalinisés, complexes, subissent de profondes transformations par réduction, puis interaction avec le milieu réactionnel. Leur sélectivité en alcools (fig. 3 varie en raison inverse de la proportion d'alcools C2+ produits. Le procédé de synthèse d'alcools (fig. 4 est fondé sur une technologie adiabatique, pour la section réactionnelle. Le fractionnement est mené par distillation azéotropique. L'intégration dans une chaîne gaz est présentée fig. 5; un rendement énergétique de 56-60% peut ainsi être obtenu. Deux démonstrations du procédé (fig. 6 ont été menées à bien et les mélanges d'alcools obtenus (tableau 5 ont fait l'objet d'essais sur flotte. Des performances typiques sont mentionnées tableau 6. Dans la chaîne gaz-alcools, la production de syngas représente 50% de l'investissement, mais la sélectivite en alcools constitue, en fait, le paramètre déterminant dans l'économie du procédé (tableau 8.

    For the synthesis of [{sup 18}F]Fluoro-Org 6141 via a nucleophilic substitution reaction with {sup 18}F{sup -}, the tosyl group was chosen as the leaving group because of its stability and excellent leaving group ability. The biodistribution of the high affinity and moderate lipophilicity (log P 2.66, calculated value) ligand [{sup 18}F]Fluoro-Org 6141 (specific activity 8.2 to 37 TBq/mmol, yield 10% at EOB) was examined in sham adrenalectomized (sADX) and adrenalectomized (ADX) male Wistar rats. Two days after ADX or sADX, the animals were anesthetized and 0.37 to 1.85 MBq of [{sup 18}F]Fluoro-Org 6141 was administered intravenously. Kinetics of {sup 18}F activity uptake were monitored for 3 h using a stationary double-headed positron emission tomography (PET) camera, and the biodistribution was assessed by ex vivo determination of radioactivity in several tissues and different brain areas. One hour after injection of the radioligand, the bladder, kidney, liver, trachea, and bone of sADX animals contained more concentration on a wet weight basis than blood. Three hours post injection, radioactivity was retained in bladder, trachea, and bone. The accumulation of radioactivity in brain corresponded to the concentration of activity in the blood within the first hours after injection. ADX animals showed a higher uptake of {sup 18}F activity in spleen, testes, and brain areas (hippocampus and brainstem) but a lower uptake in bone than sADX rats. PET scans suggested that {sup 18}F activity uptake in the brain had not yet reached a maximum at this interval. Although [{sup 18}F]Fluoro-Org 6141 is not useful for PET studies of glucocorticoid receptors (GRs), the results obtained with this compound indicate a synthetic strategy suitable for the synthesis of high-affinity radioligands for GRs.

    Full Text Available A produção de alimentos orgânicos proporciona a oferta de produtos saudáveis; o uso sustentável da água e do solo; a integridade cultural das comunidades rurais; a sustentabilidade econômica e ecológica; e a eliminação do uso de organismos geneticamente modificados em qualquer fase do processo de produção, processamento, armazenamento, distribuição e comercialização. Considerando a importância ecológica da região Amazônica, foi avaliado o mercado de consumo de produtos alimentícios orgânicos em Manaus-Amazonas e caracterizado seu perfil de consumo, potencialidade e limitações. A pesquisa foi realizada junto a Associação de Produtores Orgânicos do Amazonas. Os resultados indicaram os consumidores são em sua maioria do sexo feminino, com faixa etária entre 30 a 40 anos, nível de escolaridade superior completo, em sua maioria, com uma renda superior a 4 salários mínimos. São clientes e consumidores fiéis, porém não avaliam com critério o alimento que estão adquirindo. Os produtores encontram dificuldades principalmente no apoio do poder público à produção e comercialização, com isso a oferta não é ampla e variada, havendo a competição com os preços dos produtos gerados sem a qualidade de orgânico.

    Full Text Available Not available.A los pocos años de la creación del Consejo Superior de Investigaciones Científicas, en 1942, una escasa estancia de la primera planta del Edificio Rockefeller, hoy Rocasolano, dio base estructural a una Sección del Instituto Alonso Barba que iba a aglutinar desde entonces, con proyección de índole nacional, las mejores aportaciones a la Química Orgánica del momento. La historia del Instituto demuestra el desarrollo que tuvo en estos años en España la química orgánica en particular y cómo se fueron formando y constituyendo los nuevos equipos de investigadores. Al hilo de los grandes avances en esta rama y de la continua interacción con figuras representativas de la química orgánica europea, se establece una línea de avance y crecimiento que logra ensamblar las aportaciones teóricas con las más audaces líneas de investigación en la España de la postguerra. En ello tienen mucho que ver las figuras de sus líderes y el clima en que se iba gestando la formación de los investigadores.

    2013-06-01

    Full Text Available O crescimento do mercado de alimentos livres de agrotóxicos vem gerando interesse de agricultores em sistemas orgânicos de produção. Os adeptos deste sistema promovem mudanças substanciais de seus métodos de produção, adquirindo conhecimentos técnicos e empíricos associados. São necessários, portanto, estudos para avaliar o sistema orgânico neste contexto, comparando-o com o modo de produção convencional, no que diz respeito aos aspectos socioeconômicos e ambientais. Este estudo teve como objetivo o diagnóstico regional desses aspectos em sistemas orgânicos e convencionais do distrito de Sussuanha, município de Guaraciaba do Norte, e do município de São Benedito, no estado do Ceará. Foram entrevistados sete agricultores orgânicos e 21 agricultores convencionais, caracterizando o meio social e as mudanças de qualidade de vida ocorridas com o tempo. As interações agricultor-meio ambiente, no sistema de produção orgânico, geraram melhoria da qualidade de vida das famílias. No sistema convencional, caracterizado pelo uso intensivo de agrotóxicos e grande dependência de adubos químicos, constatou-se que prevalece o interesse em obter a máxima produção sem preocupação com o ambiente. Esta condição se reflete no contato contínuo com agrotóxicos, além das margens de lucros restritivas, o que pode comprometer o uso do solo pelas futuras gerações, pois há uma inerente redução da fertilidade natural dos solos cultivados sob este sistema.

    Full Text Available The purpose of this article is to show a more accurate orifice equation for a two-phase flow, such a compressible mixture of gas and liquid. The orifice equation given here con be used for the measurement of a gas-liquid mixture of fine emulsions by the orificemeter method. From the thermodynamic point of view, an equation of state has been formulated which provides the relationship between the specific mass of the mixture and pressure, under conditions of adiabatic expansion. The results obtained enable the mass flow rates of gas and liquid ta be determined without separation of the phases, provided thot the gas liquid mass ratio is known. The critical pressure ratio corresponding ta sonic velocity is also determined. Cet article présente une relation plus précise pour l'écoulement d'un système à deux phases, tel qu'un mélange compressible gaz-liquide, à travers un diaphragme. Cette relation peut être utilisée pour des mesures de mélanges gaz-liquide très finement divisés, c'est-à-dire des émulsions ou brouillards, par la méthode du diaphragme en paroi mince. Du point de vue thermodynamique, on a formulé une équation d'état donnant la relation entre la masse spécifique du mélange et la pression dans des conditions d'expansion adiabatique. Les résultats obtenus per-mettent de déterminer le débit massique du gaz et du liquide, sans séparation des deux phases, à condition que le rapport de masse gaz-liquide soit connu. On détermine également le rapport de pression critique correspondantà la vitesse du son.

(moringa é uma espécie vegetal com grande potencial de uso nos setores alimentício, medicinal e forrageiro, no processo de clareamento e descontaminação de água, produção de biocombustível, dentre outros. Técnicas de produção de mudas com uso de resíduos regionais são apropriadas para a introdução desta espécie em comunidades carentes. O objetivo deste trabalho foi avaliar as respostas nutricionais e de crescimento de mudas de moringa, cultivadas em substratos com diferentes concentrações de fibra da casca de coco verde (FCV, associadas a composto orgânico (CO. O delineamento experimental adotado foi em blocos casualizados. Foram testados dois compostos orgânicos: o composto de lixo urbano (CLU e o vermicomposto (VC associados a FCV em várias proporções volumétricas (CO:FCV: 0:100; 25:75; 50:50; 75:25 a 100:0%. Após 51 dias de cultivo, foi observado que o aumento da concentração de FCV em relação ao composto orgânico reduziu a altura, a massa da matéria seca, o Índice de Qualidade de Dickson e os conteúdos de N, P, K, Ca e Mg das mudas. Não houve diferença, para essas características comparando-se o uso do composto de lixo urbano e o do vermicomposto. Substratos com 100% de FCV e sem adubação complementar ocasionaram sintomas de deficiência de N nas mudas de moringa.

    The most dominant hypotheses for the pathogenesis of schizophrenia have focused primarily upon hyperfunctional dopaminergic and hypofunctional glutamatergic neurotransmission in the central nervous system. The therapeutic efficacy of all atypical antipsychotics is explained in part by antagonism of the dopaminergic neurotransmission, mainly by blockade of D(2) dopamine receptors. N-methyl-D-aspartate (NMDA) receptor hypofunction in schizophrenia can be reversed by glycine transporter type-1 (GlyT-1) inhibitors, which regulate glycine concentrations at the vicinity of NMDA receptors. Combined drug administration with D(2) dopamine receptor blockade and activation of hypofunctional NMDA receptors may be needed for a more effective treatment of positive and negative symptoms and the accompanied cognitive deficit in schizophrenia. To investigate this type of combined drug administration, rats were treated with the atypical antipsychotic risperidone together with the GlyT-1 inhibitor Org-24461. Brain microdialysis was applied in the striatum of conscious rats and determinations of extracellular dopamine, DOPAC, HVA, glycine, glutamate, and serine concentrations were carried out using HPLC/electrochemistry. Risperidone increased extracellular concentrations of dopamine but failed to influence those of glycine or glutamate measured in microdialysis samples. Org-24461 injection reduced extracellular dopamine concentrations and elevated extracellular glycine levels but the concentrations of serine and glutamate were not changed. When risperidone and Org-24461 were added in combination, a decrease in extracellular dopamine concentrations was accompanied with sustained elevation of extracellular glycine levels. Interestingly, the extracellular concentrations of glutamate were also enhanced. Our data indicate that coadministration of an antipsychotic with a GlyT-1 inhibitor may normalize hypofunctional NMDA receptor-mediated glutamatergic neurotransmission with reduced

    Full Text Available Este trabalho teve como objetivo comparar a adaptabilidade e estabilidade de cultivares de café quanto à média de produtividade anual e de biênios, pelo método de EBERHART & RUSSEL (1996, e selecionar cultivares de café para o cultivo orgânico em Minas Gerais. Os experimentos foram conduzidos em três locais, em delineamento de blocos casualizados com trinta genótipos e três repetições. Uma análise se baseou na produtividade média anual de quatro colheitas (2005/2006, 2006/2007, 2007/2008 e 2008/2009 com o total de doze ambientes. A outra análise considerou a média de dois biênios (2005/2006 e 2006/2007; 2007/2008 e 2008/2009 com o total de seis ambientes. A análise em que se considerou a média da produtividade do biênio apresentou redução expressiva do coeficiente de variação ambiental. Por isso, foi possível identificar mais cultivares com adaptabilidade e estabilidade para o cultivo orgânico. Conclui-se que a análise de adaptabilidade e estabilidade com base na produtividade de biênio é mais segura para a seleção de cultivares. Considerando essa premissa, as cultivares 'Catucaí Vermelho 36/6', 'Catuaí Vermelho IAC 15' e 'Siriema 842' são indicadas somente para os ambientes favoráveis. As cultivares 'Sabiá 708', 'IBC Palma 1', 'Catucaí Amarelo 24/137', 'Oeiras MG 6851' e as linhagens H518 e H514 são indicadas para o cultivo orgânico em locais com ambientes similares aos avaliados em Minas Gerais.

    Full Text Available OBJETIVO: Avaliar a resposta biológica e poder indutor da combinação matriz óssea orgânica bovina e hidroxiapatita. MÉTODOS: Foram produzidos defeitos ósseos em crânios de 20 ratos, Wistar, machos, com peso inicial médio entre 300 e 350 gramas, divididos eqüitativamente em dois grupos. No grupo I o defeito foi preenchido com uma associação de matriz óssea orgânica bovina e hidroxiapatita, ao passo que no grupo II considerado controle, nada foi empregado. Para o estudo histológico foram submetidos à eutanásia, cinco animais de cada grupo, aos 30 e 60 dias de pós-operatório. RESULTADOS: Com 30 dias de pós-operatório a reabsorção óssea foi maior no grupo II. A presença de cartilagem não diferiu entre os momentos de um mesmo grupo, porém houve diferença estatística entre os grupos I e II aos 30 dias, sendo maior no grupo I. Aos 60 dias de pós-operatório, o grupo I apresentava uma maior quantidade de osteoblastos e presença de osso comparativamente ao grupo II. CONCLUSÃO: A combinação matriz óssea orgânica bovina e hidroxiapatita não causa reações adversas e favorece a reparação óssea.

    Full Text Available Objetivou-se, neste trabalho, avaliar os efeitos da cobertura do solo e da adubação orgânica sobre a temperatura e a umidade do solo, a incidência de plantas daninhas e a produtividade da alface. O delineamento experimental utilizado foi de blocos casualizados, em esquema fatorial (3 x 3, em que o primeiro fator corresponde aos tipos de cobertura morta (capim tifton, capim napier e ausência de cobertura e, o segundo, aos adubos (esterco bovino, esterco de galinhas e ausência de adubação. Analisaram-se as variáveis temperatura e umidade do solo, o número de folhas produzidas pela alface, as massas de matéria fresca e seca da parte aérea, das plantas de alface e daninhas, e o levantamento fitossociológico das plantas infestantes. As plantas adubadas com esterco de galinhas apresentaram massas de matéria fresca e seca superiores às das plantas não adubadas. A cobertura morta com capim tifton proporcionou aumento da massa de matéria seca das plantas de alface, o que pode estar relacionado com a menor temperatura dos canteiros que receberam esse material como cobertura. Commelina benghalensis foi a planta infestante mais importante no cultivo orgânico de alface. A aplicação de adubos orgânicos e a cobertura morta com capins não foram capazes de suprimir plantas daninhas e manter a umidade do solo, em áreas de cultivo de alface.

    Full Text Available Este trabalho teve como objetivo estudar a natureza química das frações leves-livres (FLL e leves intra-agregado (FLI da matéria orgânica do solo, obtidas pelo fracionamento físico do solo por densidade, por meio da espectroscopia na região do infravermelho, para verificar se tais frações constituem compartimentos distintos da matéria orgânica do solo. Foram analisadas amostras de Latossolos de dois estados do Brasil (RS e GO, submetidos a plantio direto e preparo convencional, em distintos sistemas de rotação de culturas. A análise por infravermelho revelou diferenças contrastantes entre os compartimentos orgânicos estudados. Os espectros de IV da fração leve-livre apresentaram configuração semelhante aos dos resíduos vegetais, indicando que ela se encontra em estádios iniciais de transformação. Não foram observadas diferenças estruturais na FLL entre os distintos sistemas de preparo e rotação de culturas. Os espectros de IV da FLI apresentaram bandas de absorção N-H e C-O de polissacarídeos menos intensas e em maior conjugação, em relação aos espectros da FLL, características de material mais humificado. Foi observada ainda uma maior transformação estrutural da fração leve intra-agregado em solos sob preparo convencional, quando comparada à FLI de solo sob vegetação natural e plantio direto. Os índices de hidrofobicidade (IH e de condensação (IC, determinados a partir de relações entre as bandas de absorção de grupamentos - CH3 alifáticos, C-O de polissacarídeos e C=O conjugados, permitiram identificar as diferenças na recalcitrância e condensação das frações leves. Constatou-se que ambos os índices foram significativamente maiores para a matéria orgânica intra-agregado, por conseqüência de seu maior grau de humificação.
